This presentation covers some important facts about supernovae. It will be a great help if you can leave a comment (or suggesions if any).

1. THE PHYSICS BEHIND
INTERSTELLAR
FIREWORKS

3. Outline
Stellar evolution
Supernovae
Types of supernovae
Mechanisms of supernovae
Supernova detection
Importance of supernovae

4. Stellar evolution
The
changing of
stars with
time

8. What is a
supernova?
• One of the most powerful and
spectacular events in the universe.
• A bright explosion
• Marks the death of a star
• Releases a large amount of energy
(about 1044 J)
• Shines with high luminosity (sometimes
equivalent to the brightness of about 10
billion suns)

9. Types of
supernovae
Supernovae
Type I Type II

10. Mechanisms of
supernovae
White dwarf supernovae – Type Ia
the accretion of mass from the partner in
a binary star system

13. Mechanisms of
supernovae …
Massive star supernovae
Type II, Type Ib, Type Ic
core collapse

14. Core collapse
Undergoes an extended sequence
of thermonuclear reactions

17. Supernova
detection
At first the supernovae were observed with
naked eyes.
For this the luminosity of the supernova
should be high.
With the invention of telescopes it became
possible to observe supernovae
»In other galaxies
»With less luminosities

18. Major types of telescopes
used
Optical
telescope
X-ray
telescope
Radio
telescope

19. Importance of
supernovae
Distance measurements
Evidence for accelerating
expansion of the universe
Distribution of elements
Stimulating nebulae for star
formation

20. Summary
Stellar evolution
Supernovae
Types of supernovae
Mechanisms of supernovae
Supernova detection
Importance of supernovae
