Stars are powered by fusing hydrogen, not oxygen. A star that has exhausted the hydrogen in its core may continue to burn as a red giant.
A star that has exhausted the hydrogen in its core will become a red giant or supergiant.
A star that is a white dwarf has exhausted its supply of hydrogen.
During a super-nova, a star explodes its outer-layers into a gaseous state. The massive explosion is triggered by the nuclear fusion in the core of the sun. The prossess of the elements fusion are hydrogen, helium, oxygen, carbon, iron, and uranium. Uranium is only found in hypergiant stars. When all of the fule is exausted, the star explodes each shell in order, until a white dwarf, nuetron star, or a black hole is left.
A star that has exhausted the hydrogen in its core will become a red giant or supergiant.
A star that has used up it's hydrogen supply because a "Red Giant". The star increases in diameter as it turns into a red giant.
Yes
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity. Core contracts, temperatures incrase. This causes outer layers to expand and cool. This star is called a GIANT.
The first star born
A star that is forming is called a protostar.
No. A star is born when hydrogen stars fusing.
The north star is a star, not a planet. It is called Polaris. The planet Venus is called the Evening Star
Mostly in planetary nebulae where a star that was big enough to produce oxygen when it exploded is.
