What are the Stages of a star?

Answer 1

nebula then protosar then red dwarf, yellow star or a blue giant then a red giant then a red super giant then eithr a white dwarf or a supernova from the supernova a black hole or a neutron star if it is a white dwarf it turns into a black dwarf then a black hole

• Nebula
• Baby star
• Star
• Giant or supergiant
• White dwarf
• Black dwarf

Answer 2

An averagely massive star's lifecycle will often follow the main sequence. It will fuse hydrogen into helium for most of it's life. Eventually when the star runs out of hydrogen (About 9-10 billion years), the core partially collapses, increasing the pressure and heat inside the core high enough to allow it to fuse the helium into carbon. This is the beginning of the red giant phase. Once it runs out of helium, another core collapse occurs, now allowing it to fuse the carbon into neon, then neon into oxygen, oxygen into silicon and finally silicon into nickel which decays into iron. At this point, if the star's core is dense enough, the core will collapse into either a super-dense neutron star, who's core collapse is halted by electron degeneracy or total collapse into a gravitational singularity. Either way, once the core collapse has ended, all the matter the core took with it is shot back in a shockwave called a supernova or hypernova.
The white stage, when it is small and young, the orangish yellowish stage, when it starts to grow more, the red giant stage, when it gets really big, the bluish stage, when it is huge, and then the white dwarf stage, when it has no energy, and the black dwarf stage when it cools off. The giant stars sometimes become black holes though.
