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 the first pulsar, a type of neutron star. Neutron stars come in different types, including pulsars which emit beams of electromagnetic radiation and magnetars which have extremely powerful magnetic fields.
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 formed by
death of stars.
5. 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.
7. Facts about neutron star
• It’s mass is in between one and three
sun.
• Neutron star is about 20 km in diameter
• It’s mass is so dense that electron enters
the nucleus and forms a neutron by the
process of electron capture
• e + p
9. Pulsar
• A Pulsar is a highly
magnetized,
rotating neutron star.
• That emits a beam
of electromagnetic
radiation.
• This radiation can
only be observed
when the beam of
emission is pointing
toward Earth
10. Magnetar
• A magnetar is a type
of neutron star with
an extremely
powerful magnetic
field.
• The magnetic field
decay powers the
emission of high-
energy
electromagnetic
radiation, particularly
X-rays and gamma
rays.
12. Neutron star Vs black hole
• Neutron star stand
nothing infront of
black hole
• Because gravity of
black hole is much
more the that of
neutron star
14. 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.
