Brighton Astro - Neutron Star Presentation
Neutron stars are extremely dense collapsed cores of massive stars. They form through the supernova explosion that occurs when stars over 1.4 times the sun's mass reach the end of their life cycles. Neutron stars can have masses over twice the sun's yet be only 20 kilometers wide, making them incredibly dense. They exhibit a variety of behaviors depending on their spin rates and magnetic fields, including pulsating beams of radiation, powerful bursts of x-rays and gamma rays, and warping of spacetime from their intense gravity. It is estimated there are over a billion neutron stars in the Milky Way galaxy.
Neutron Star
Pulsars are powered by the loss of rotational energy or by accretion of infalling matter. Magnetars are pulsars with extremely strong magnetic fields that provide their power. Neutron stars are formed during the gravitational collapse of massive stars over 8 times the mass of our Sun in a supernova explosion. They are only about 20 km in diameter but have around 1.4 times the mass of our Sun, making them incredibly dense - a teaspoon of neutron star material would weigh over a billion tons on Earth.
Neutron star
A neutron star is formed by the gravitational collapse of a massive star after a supernova. It has a mass of 1-3 times the sun's mass but is only about 20 km in diameter, making it incredibly dense. The first neutron star was discovered in 1967 by Jocelyn Bell, a graduate student who discovered a pulsar, a type of neutron star that emits beams of electromagnetic radiation. Neutron stars come in different types, including pulsars which are highly magnetized and rotating neutron stars that emit beams, and magnetars which have extremely powerful magnetic fields that power their emission of high-energy radiation.
Neutron stars basics
Neutron stars are extremely dense remnants of dead stars approximately 4-8 times the mass of the Sun that have collapsed into a city-sized object composed almost entirely of neutrons. They form when a massive star runs out of fuel and collapses under its own gravity, compressing its core into neutrons. Neutron stars can spin hundreds of times per second and have immense gravitational pulls billions of times stronger than Earth. They emit radiation known as pulsars and have some of the strongest magnetic fields in the universe. Neutron stars can survive for billions of years as they slowly cool.
Dark matter
Dark matter is invisible matter that makes up about 21% of the universe. It cannot be seen directly but its existence and properties are known through its gravitational effects on visible matter. There are two main types of dark matter: ordinary matter made up of normal particles and extraordinary dark matter like black holes. Dark matter was first proposed in 1933 by Fritz Zwicky to explain discrepancies in galaxy motions but its exact nature remains mysterious. Current experiments aim to detect dark matter particles but have had conflicting results so far.
Dark matter
Dark matter is an invisible phenomenon that acts on visible matter through gravity. It accounts for 6 times more mass in the universe than normal matter. Fritz Zwicky discovered evidence of "invisible matter" in galaxies in 1933 while Vera Rubin provided further evidence in the 1970s, though they were initially disregarded. String theory may help explain dark matter through postulated supersymmetric particles. Dark energy is a hypothetical form that permeates space, causing accelerated expansion of the universe, and may account for most of its mass. It produces an opposite effect to gravity. String theory also provides several potential explanations for dark matter through concepts like supersymmetric particles, branes, and extra dimensions.
Neutron stars and white dwarfs
Neutron stars are extremely dense collapsed stars sometimes left behind after a supernova explosion. They are created when giant stars die in supernovas and their cores collapse, compressing the protons and electrons into neutrons. Neutron stars have a diameter of only 20 kilometers but contain 1.5 times the mass of the Sun concentrated into that small, dense space. White dwarfs are stellar remnants composed mainly of electron-degenerate matter. They have a mass comparable to the Sun's but contained within a volume comparable to Earth's. In the future, as the Sun dies it will expand into a red giant, engulfing the inner planets, before collapsing into a hot, dense white dwarf.
Dark matter and dark energy (1)
This document discusses gravity and its role in shaping astronomical structures like galaxies and galaxy clusters. It describes how gravity causes stars at the edges of spiral galaxies to rotate at similar speeds to those at the center, and how galaxy clusters contain 10 times more mass than can be accounted for by visible matter alone. The document also mentions how Einstein's theory of general relativity explains the accelerating expansion of the universe driven by dark energy, which exerts a repulsive force that counteracts gravity on large scales.

A supernova is a massive stellar explosion that occurs at the end of a large star's life. There are two main types of supernovae that can form - Type I occurs when a white dwarf star accumulates too much matter from a nearby star, and Type II occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. During its explosion, a supernova can outshine its entire host galaxy and radiate more energy than our Sun will over its entire lifetime, making them the primary source of heavy elements in the universe.
Dark matter and Dark energy
Dark matter makes up about 5 times as much of the matter in the universe as regular matter, though its composition is unknown. It interacts very weakly and was first discovered through its gravitational effects on galaxy rotations. Dark energy makes up about 75% of the universe and is causing its accelerating expansion, though the source is a mystery and quantum effects predict a much larger value. String theory landscape ideas may help explain the observed size of dark energy through vacuum selection in a complicated potential.

Dark matter and dark energy
Dark matter makes up 73% of the universe and is composed of unknown particles that do not emit or absorb light but have gravitational effects. Dark energy is 23% and is a repulsive force that is driving the expansion of the universe. Both dark matter and dark energy were hypothesized to explain inconsistencies in cosmological theories and observations of the structure and acceleration of the expanding universe.
Dark matter presentation
Dark matter is matter that does not emit or absorb light or radiation and can only be detected through its gravitational effects. It makes up 23% of the universe's energy. Its exact particle nature remains unknown. Dark matter was first hypothesized to account for discrepancies between the mass of large astronomical objects determined by their gravitational influence versus the mass calculated from the visible matter they contain. Understanding dark matter is important because it and dark energy make up over 90% of the universe's total energy.
Neutrino
Neutrinos are elementary particles that have no electric charge and interact very weakly with matter. There are three types of neutrinos related to electrons, muons, and tau particles. Neutrinos are abundantly produced in nature by the sun, stars, and nuclear reactions. They pass through the body without interacting but can be detected underground using large detectors composed of layers of iron and detectors that observe the curvature of charged particles produced during neutrino interactions, revealing information about the neutrinos' energy. The INO laboratory under construction in India will also study neutrinos.
Dark matter & dark energy
Dark matter and dark energy make up 95% of the universe. Dark matter is an undetected form of matter that exerts gravitational pull but does not emit or interact with light. Its existence is inferred from its gravitational effects, such as the rotation speeds of galaxies. Dark energy is driving the accelerating expansion of the universe according to Hubble's law, contradicting the expected eventual gravitational collapse. While their effects can be observed, the true nature of dark matter and dark energy remain mysterious, as they have not been directly detected, and may hold potential future applications in spacecraft propulsion if their properties can be better understood.

Chapter 22.3 : Nuclear Radiation
The document discusses key concepts related to nuclear radiation including:
1) Defining the units roentgen and rem used to measure radiation exposure and dose, distinguishing that rem factors in human tissue effects.
2) Describing three common radiation detection devices - film badges, Geiger-Müller counters, and scintillation counters.
3) Outlining applications of radioactive nuclides including radioactive dating, medical uses like cancer treatment, tracing movement in the body, and extending food shelf life.
Physics seminar
The document provides information about the Global Positioning System (GPS). It describes GPS as a satellite-based navigation system developed by the US Department of Defense, consisting of 24 satellites that provide accurate positioning worldwide without fees. It explains how GPS determines a location by measuring the time it takes signals from satellites to reach a receiver and calculating distance based on travel time and speed of light. The document discusses sources of error and how GPS accuracy is evaluated. It also lists applications of GPS and provides tables of operational GPS satellites with launch dates.
Nuclear radiation detector
Nuclear radiation detectors detect nuclear particles and radiation. They work by exciting or ionizing the atoms in the material they pass through. There are different types of radiation including charged particles like alpha and beta particles, uncharged neutrons, and electromagnetic gamma rays and x-rays. Detection methods are based on the radiation interacting with the detector's base material, often ionizing or exciting its atoms. Detectors are classified as gas filled, ionization chambers, Geiger-Muller counters, semiconductors, Wilson cloud chambers or bubble chambers. Their workings exploit the properties of ionization, fluorescence, or exposing photographic plates.
Radioactivity
The document summarizes the history and key discoveries related to radioactivity and nuclear physics. It discusses how Becquerel discovered radioactivity in uranium in 1896, leading the Curies to isolate the elements polonium and radium. It then covers atomic structure, the different types of radioactive decay, units of radioactivity, decay processes, and nuclear reactions including fission and fusion.
Dark matter
Dark matter is an invisible form of matter that accounts for about 85% of the matter in the universe. It was first proposed in 1933 to explain unexpected motions of galaxies, and its existence and properties have since been further confirmed by various observations, though its exact nature remains unknown. Dark matter is distinct from dark energy, which is driving the accelerating expansion of the universe. Leading candidates for dark matter include WIMPs (Weakly Interacting Massive Particles) such as neutralinos and axions.
Pelletron and van de graff generator
The document discusses a Pelletron tandem accelerator. A Pelletron uses a chain of metal pellets and insulating connectors to generate a high voltage on its terminal, allowing for tandem acceleration of ions. It operates similarly to a Van de Graaff generator but can achieve higher voltages and currents. Ions are produced, accelerated twice in opposite directions, steered, and directed into scattering chambers. Applications include materials analysis, medical uses, and industrial processes like radiation production and sterilization.
Dark Energy And Dark Matter
Observations from the Hubble Space Telescope in 1998 showed that the universe was expanding more slowly in the past than it is today, contrary to expectations. This led scientists to propose either modifications to Einstein's theory of gravity, such as the introduction of dark energy, or the existence of an unknown type of matter, dubbed dark matter, that cannot be detected directly. Dark matter is inferred to make up about 27% of the universe based on its gravitational effects, but its exact nature remains unknown.
Dark Matter And Dark Energy
Dark matter is believed to be made up of weakly interacting massive particles and holds galaxies together through gravity, though it does not emit or reflect light. Dark energy is the energy of empty space that is accelerating the expansion of the universe. Understanding dark matter and dark energy could allow for faster-than-light travel and more thorough astronomical research. Only 5% of the universe is visible matter - 25% is dark matter and 70% is dark energy.
Black holes (2)
Black holes are formed when giant stars collapse under their own gravity. If the star's mass is large enough, its gravitational pull becomes so strong that not even light can escape, forming an event horizon around the black hole. Anything that crosses this boundary, including light, cannot escape the black hole. Black holes can also rotate, forming an ergosphere outside the event horizon where the rotation of the black hole drags spacetime itself along. While black holes themselves are invisible, astronomers can detect them through their interaction with nearby matter and the strong gravitational lensing they produce.

Neutron stars
The document discusses neutron stars and pulsars. It begins by outlining predictions about neutron stars, including their small radius of 10-80 km but large mass over 1.4 times the sun's mass. It then explains how conservation of angular momentum causes neutron stars to spin rapidly as the core collapses. The discovery of pulsars is summarized, including how their periodic emission can be explained by a rotating misaligned magnetic field. The document concludes by briefly introducing black holes and relating them to Einstein's theory of general relativity.
Astonishing Astronomy 101 - Chapter 6
This document summarizes key components and concepts about the structure of the solar system:
- The solar system consists of the Sun, eight planets, dwarf planets, asteroids, comets, and other small bodies. The Sun contains over 99% of the solar system's mass.
- The inner terrestrial planets are rocky, while the outer gas giants are large planets composed primarily of hydrogen and helium. An asteroid belt exists between Mars and Jupiter.
- Factors like a planet's mass, distance from the Sun, composition, and atmospheric properties help determine its environment and surface conditions. Larger planets retain heat and atmospheres better than smaller ones.
- Techniques like radioactive dating indicate the solar system formed
The Beginning of the Universe
The document provides information about several theories of the origin and evolution of the universe and solar system. It discusses the Big Bang theory, which proposes that the universe began in an extremely hot and dense state and has been expanding ever since. It also describes theories for how the sun, planets, and natural satellites formed, such as the nebular hypothesis which suggests they formed from a rotating cloud of gas and dust. The document then gives details about the properties of planets in our solar system as well as dwarf planets like Pluto.

This document provides an overview of human understanding of the universe over the past 3000 years. It begins with ancient Greek philosophers' early concepts of astronomy and the structure of the universe. It then discusses the major scientific breakthroughs from the 15th century onward that led to modern cosmological theories, including the work of Copernicus, Kepler, Galileo, Newton, Maxwell, Einstein and others. The document concludes by noting some of the key discoveries of the early 20th century that helped establish modern physics and our current understanding of the universe.
The life cycle of a star
The document outlines the life cycle of stars from birth in nebulae of gas and dust through their main sequence phase, later evolution into red giants, and final stages as white dwarfs, neutron stars, or black holes. It describes how gravity pulls gas together in nebulae to form protostars, which become main sequence stars fueling nuclear fusion for millions of years. As hydrogen runs out in their cores, more massive stars explode as supernovae while lower mass stars expand into red giants then contract into white dwarfs.
Apes earth systems
The document summarizes the origins and evolution of the universe, galaxy, solar system, and Earth. It begins by explaining how the Big Bang occurred approximately 13.7 billion years ago, marking the expansion of the early universe. It then describes how the universe cooled and formed elemental structures, galaxies, stars, and planets over billions of years. Specific details are provided about the formation of the Milky Way galaxy and solar system, including Earth. The geological history of Earth is outlined, dividing time into eons, eras, periods, and epochs marked by significant evolutionary changes and extinctions.

1) Stars form from dense fragments within interstellar clouds that collapse under gravity over millions of years.
2) Protostars form within the collapsing fragments and grow in mass through accretion until their cores reach temperatures high enough for nuclear fusion.
3) After 10 million years, the protostar becomes a true star on the main sequence, where nuclear fusion powers the star for its lifetime.

The document provides information about the universe and solar system. It discusses:
- The universe is approximately 13.8 billion years old and consists of dark energy, dark matter, and normal matter.
- The solar system formed from a collapsing cloud of gas and dust around the sun approximately 4.6 billion years ago. Planetesimals collided and accreted to form the planets.
- The current model is that the sun and planets formed from a protoplanetary disk, with collisions forming the terrestrial planets close to the sun and condensation forming the gas giants further out.
Presentation History of the Universe_p.ppt
The document provides an overview of the prevailing Big Bang theory of the origin and evolution of the universe. It describes how approximately 13.7 billion years ago, all matter, energy, space, and time were compressed into a singularity which then began rapidly expanding. As it expanded and cooled, the fundamental forces separated and various phases occurred, including the formation of hydrogen, helium, stars, galaxies, and eventually life on Earth. The Big Bang theory is considered the best explanation for observations of the composition and structure of the universe.
Astonishing Astronomy 101 – Chapters 14 and 15
This document summarizes information about the solar system and beyond. It discusses the reclassification of Pluto as a dwarf planet in 2006 based on its size and inability to clear its orbital neighborhood. It also describes the discovery of new moons around Pluto in 2005 and 2006. The document discusses other large trans-Neptunian objects like Eris, Sedna, and Quaoar. It provides information on comets, asteroids, meteoroids, and meteorites. It discusses theories on the origin of comets from the Oort cloud and Kuiper belt and describes comet tails and nucleus. The document summarizes crater formation from meteorite impacts and mass extinction events. It also discusses finding exoplanets using the radial velocity
14 lecture outline
The Sun shines through nuclear fusion in its core. The core is hot and dense enough for hydrogen to fuse into helium via the proton-proton chain reaction. This nuclear fusion releases energy that gradually makes its way to the surface and radiates into space, powering the Sun for billions of years. We know about the Sun's interior structure from mathematical models, observations of solar vibrations, and detections of solar neutrinos. Solar activity like sunspots and solar flares are caused by magnetic fields in the Sun. Bursts of particles from solar activity can disrupt power grids and satellites orbiting Earth. The 11-year solar cycle is due to changes in the Sun's magnetic field over time.

Evolution of universe
The document discusses the evolution of the universe from the Big Bang theory to present day. It covers:
1) The Big Bang theory which proposes the universe began as a hot, dense point around 14 billion years ago and has been expanding and cooling ever since.
2) The formation of stars, galaxies, and planets as the universe evolved, with our solar system forming around 5 billion years ago.
3) Two other theories - the Steady State theory which proposes the universe has always existed in a constant state, and the Pulsating universe theory.

Neutron star ,an interesting part of astronomy.
- 1. NEUTRON STAR Presented by Md. Sobur Hossain
- 2. WHAT IS A NEUTRON STAR • A neutron star is a type of compact star that can result from the gravitational collapse of a massive star after supernova. • Neutron stars are created when giant stars die in supernovas and their cores collapse, with the protons and electrons essentially melting into each other to form neutrons. • Neutron stars are formed by death of stars.
- 3. Discovery of neutron star • The first neutron star was discovered by 24-year-old graduate student Jocelyn bell in 1967. • she discovered the first pulsar a type of neutron star.
- 4. LIFE CYCLE OF STARS
- 5. Formation Of Neutron Star 1.Any main-sequence star with an initial mass of above 8 M☉ has the potential to produce a neutron star. 2. When evolves from main sequence, all nuclear fuel in the core has been exhausted and the core must be supported by electron-degeneracy pressure is overcome and the core collapse which exceed the Chandrasekhar limit. 3.Through photodisintegration process the temperature climbs even higher, electrons and protons combine to form neutrons via electron capture, releasing a flood of neutrinos. •4. When nuclear density reaches of 4×1017 kg/m3, neutron degeneracy pressure halts the contraction. The infalling outer atmosphere of the star is halted and flung outwards by a flux of neutrinos produced in the creation of the neutrons, becoming a Type II or Type Ib supernova. The remnant left is a neutron star.
- 6. IMPORTANT FACTS • For the formation of black hole the size of the star should be 30 times more than that of sun. • If the size of the star is less than 30 times of that of the sun then it will be converted into neutron star • Neutron star spins very fast. • The earth period 1 day(86,400 seconds); wheather neutron star period ~ 0.01 seconds • gravity on a neutron star is 2 billion times stronger than gravity on Earth.
- 7. Facts about neutron star • It’s mass is in between one and three sun. • Neutron star is about 20 km in diameter • They are so dense that a normal-sized matchbox containing neutron-star material would have a mass of approximately 13 million tonnes. • It’s mass is so dense that electron enters the nucleus and forms a neutron by the process of electron capture • e + p
- 8. INTERNAL STRUCTURE OF NEUTRON STAR
- 9. Nearest neutron star • Astronomers using X-ray telescope have detected a neutron star within 250 to 1,000 light-years of Earth, making it the closest neutron star ever known. • There is zero possibility that a neutron star will going to hit the earth.
- 10. Types of neutron star • Pulsar • Magnetar
