Stars form when enough hydrogen accumulates to cause enough internal pressure and heat to make the ball of hydrogen glow from the fusion of hydrogen to form helium. Depending on the size and temperature of the new star, it will fall along the HR Diagram as a class O,B,A,F,G,K or M star. Class O stars are very big and very hot, giving off blue/white light. Class M stars are small, cool red dwarf stars. Our sun is a class G star, a small star which burns moderately and is yellow.
Depending on the mass of the star, it will burn at different rates. Class O and B stars, although large, burn very fast because they are so hot. Class M stars, being small and cool, can burn for many millions of years longer.
Eventually, all stars run out of fuel and begin to collapse on themselves. What happens next depends on the type of star.
Large, hot stars will explode in a supernova, ejecting their entire blanket of gases into space and leaving behind a small core which will be a pulsar (neutron star), or even a black hole.
Medium stars like our sun will swell their outer layers to become Red Giants (such as Betelguese in Orion). This phase will last for a few million years until the core finally cannot support the outer layers any longer. To give you an idea of size, our sun will eventually send it's outer layers as far out as to engulf Mars.
Once these moderate Red Giants run out of fuel, they collapse and form a white dwarf star, which will be the end result of our sun. After billions of years, they will cease to glow and become black dwarfs. (Do not confuse this with black holes..completely different).
Small red dwarf stars will puff out outer layers in a planetary nebula, but will not have enough energy to explode. They will eventually become small black dwarf stars as they lose their energy and can no longer burn.
This is very brief because this is a very complex process, but I hope this helped.

What are the star life cycle that are accurate?
The stages in a star's life cycle are: formation from a nebula, main sequence (where it fuses hydrogen into helium), red giant or supergiant phase, depending on the star's mass, and finally either collapse into a white dwarf, neutron star, or black hole. This life cycle is accurate for most stars, including our Sun.
What the star life cycle the is accurate?
Star of one stellar mass, red giant, white dwarf, planetary nebula
What is the life cycle of the star capella?
What is capella star life cycle
Where is the earth on the star life cycle?
The "star life cycle" refers to stars. Earth is not a star.
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
compare your life to the life cycle of a star?
How does the life cycle of humans compare to the life cycle of a star? They both have stages where they are born and die which is in the main sequence and supernova and in a human they are born in a womb and die of old age.
Who invented the life cycle of a star?
Nobody "invented" it, the life cycle of stars happens naturally.
What determines the life cycle of a star?
its mass
What has a life cycle similar to a star?
A dog.
Select the star life cycle that is accurate.?
Star of three stellar masses, Red giant, Supernova, Neutron Star Hope this helps! :) 5/3/21
What is the star life cycle of the sun?
Life cycle of a sun like star. A sun like star will start out as a nebula to a protostar to a main sequence star to a red giant and into a white dwarf and will simply fade out.
Select the star cycle that is accurate?
Star of one stellar mass, red giant, white dwarf, planetary nebula
