Stars of the main sequence with masses about 9 times as large as our Sun will normally form supernovas, the cataclysmic explosion of the star.
When they near the end of their hydrogen-to-helium fusion cycle, the heat and pressure inside the star can begin further fusion reactions in various layers (helium-to-carbon, carbon-to-neon, neon-to-oxygen, oxygen-to-silicon, and silicon-to-iron). Eventually, however, the outward force of these reactions can no longer support the gravitational weight of the outer layers. When they collapse, they trigger an explosive compression and rebound that blows off a large proportion of the star's mass.

What kinds of stars are pulsars a form of?
First [may be partial] is: A Cephid Variable Star. Quasars and other Gamma Ray sources [colliding Neutron Stars, and 'coalescing' Pairs of Black Holes for example] are also closely related.
Name the gases that make up most stars?
Hydrogen and helium. It's better to ask which two ELEMENTS make up the bulk of the stars, since ALL elements in a star are in the gaseous state.
Do Stars have points?
No. Real stars do not points.
Where do scientists get carbon to create star fuel?
Scientists do not make "star fuel," and stars, for the most part are not fueled by carbon, anyway. Stars are mostly fueled by hydrogen which was formed in the very early history of the universe, shortly after the "Big Bang." To learn more about how stars formed and what make them "burn", you should go to a website like http://www.kidsastronomy.com/

Do most massive stars collapse into black holes?
Most stars end up as white dwarfs. A few become neutron stars. Even fewer become black holes.
Do medium size stars become black holes true or false?
False. Only the most massive stars will become black holes.
How do some stars become shooting stars?
Shooting stars are not stars. They are bits of dirt and dust that burn up in our atmosphere, briefly making them look like stars. Most of that is debris is from comets or others bits of dirt in space, but they are not stars and were not stars. So stars do not become shooting stars.
Which stars primarily end up as black holes?
The most massive stars become black holes.
Medium size stars become black holes true or false?
False. Medium-sized stars become white dwarfs. Only the most massive stars form black holes.
Why do stars not become red giants?
Most medium mass stars such as our Sun DO become red giants. Smaller stars do not have enough mass to initiate helium fusion when the hydrogen supply begins to run low, and do not become red giants.
Are dead stars black holes?
Yes. They get sucked into black holes all the time!
Do all stars that become supernovae leave behind a neutron star?
No. The most massive stars will leave behind a black hole.
Do you think there are more white dwarfs or more black holes in the universe?
More white dwarves. Most stars will become white dwarves at the end of their lifetime. On a "select few" will become black holes - the most massive stars.
What will happen when a star exhausts its remaining fuel?
Most stars will become white dwarf stars. A "high mass" star will become a neutron star or a black hole, after exploding as a supernova.
Do massive stars become neutron stars?
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
What is the difference between stars that become white dwarfs stars that become neutron stars and stars that become black holes?
The difference is in mass. Low to medium mass stars (up to about 8-10 solar masses) become white dwarfs. Massive stars (10 to 25 solar masses) become neutron stars. Stars above 25 solar masses tend to become black holes.
