The life of an average star typically progresses through four stages: first, it forms from a collapsing cloud of gas and dust, becoming a protostar. Next, it enters the main sequence phase, where it fuses hydrogen into helium in its core, sustaining itself for billions of years. After exhausting its hydrogen, it expands into a red giant and begins fusing helium into heavier elements. Finally, the star sheds its outer layers, leaving behind a white dwarf that gradually cools and dims over time.
Usually it's from nuclear fusion. At some stages in a star's life it can get a lot of energy from gravitational collapse.
The mass of a star is the primary factor that determines the stages it will go through during its life cycle. Stars with different masses will undergo different evolutionary paths, such as fusion of different elements and eventual fate (e.g., white dwarf, neutron star, black hole).
The color of the supergiant star Betelgeuse reveals its stage in its life cycle. Betelgeuse appears red because it is a cool, aging star that is at the latter stages of its life, in the red supergiant phase.
Ultimately the mass a star has at the end of its life depends on its initial mass. This mass determines what stages a star will go through in its death throws.
Yes, in comparision with the rest of the universe, our Sun is a relatively young star.
Our Sun is an average star and it has an approximate lifespan of
protostar
-average size -expands and becomes a red giant -cools and contracts, becomes a white dwarf star -massive sized stars -swell and become red supergiants -explode (called a supernova) -become a black hole -become a neutron star
The average star will become a white dwarf at the end of its life.
Usually it's from nuclear fusion. At some stages in a star's life it can get a lot of energy from gravitational collapse.
It is approx half-way through its 10 billion year life cycle.
Giants and super giants are considered stages in 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.
Our Sun is an average star and has a life time of approximately 10 billion years.
The mass of a star is the primary factor that determines the stages it will go through during its life cycle. Stars with different masses will undergo different evolutionary paths, such as fusion of different elements and eventual fate (e.g., white dwarf, neutron star, black hole).
