gravity
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.
Gravity acts to pull matter inward, causing a star to contract and increase density. Fusion, on the other hand, generates energy by fusing hydrogen nuclei to form helium, resulting in outward pressure that counteracts gravity and maintains the star's stability.
Our Sun is the star that continues to use hydrogen for energy through nuclear fusion in its core. The heat generated from this fusion process creates outward pressure that balances the inward pull of gravity, allowing the Sun to remain stable and shine brightly.
A star that has collapsed under gravity and is made of neutrons is called a neutron star. Neutron stars are extremely dense and have a strong gravitational pull due to the collapsed core of a massive star. They are the remnants of supernova explosions.
In a star a balance exist between gravity shrinking and expansion due to fusion energy released.
yes, the sun has gravity. more gravity that us. if you were quite away from it, it would pull you in! the pull is caused by gases forming up and it gets so strong, like the wind, it pulls you in its direction. It is a star, which is formed of gas. the sun is a big star though, so it has more gas, which means it has more pull.

A protostar will stop shrinking and stabilize into a star when the inward force of gravity is balanced by the outward pressure generated by nuclear fusion in its core. This marks the beginning of the star's main sequence phase where it will remain stable for several billion years.

Normally gravity from a passing star or planet will pull it toward it.But how does the gas get there?I'm asking you.
Yes. When a star dies for example, the inward gravitational pull is so dense that it creates a black hole!
when a star is attracted by the atmosphere of the earth it is pulled by the gravity so when is pulled friction is caused between the air and the star and it catches fire so it becomes a shooting star.
in a protostar before fusion ignites, gravity.in a normal star, fusion.in a star at the end of its life when fusion burns out, gravity. This is what drives the final blast of a supernova explosion.
