Gravity pulls the material together and it heats up to the point when self sustaining nuclear fusion starts.
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.
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.
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
They Collide and become part of another star which causes Stars to be come Parts of other Stars.
No. Stars such as our sun become white dwarfs. Only stars 8-10 times the mass of the sun or more become neutron stars.
There are three types of stellar remnants. Low to medium mass stars will become white dwarfs. High mass stars will become neutron stars. Very high mass stars will become black holes.
Stars are tremendously larger than asteroids and do not become asteroids.
Not all protostars become true stars. Some protostars may not have enough mass to sustain nuclear fusion in their cores and never become true stars, instead becoming failed stars known as brown dwarfs.
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.
No. Only massive stars can become supergiants.
Main-sequence.
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
