The correct life sequence of a star starts with a protostar, which forms from a dense cloud of gas and dust. The protostar then evolves into a main sequence star, where it fuses hydrogen atoms to form helium in its core. Depending on its mass, the star will either become a red giant or a supergiant before eventually shedding its outer layers to become a white dwarf, neutron star, or black hole.

What does it mean when a star goes off the main sequence?
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
Is Vega on the main sequence?
Vega is a main sequence star. About half way through it's life, but evolving rapidly.
Identify what kind of a star is the sun?
Our sun is a main sequence star - in the middle of it's life and relatively stable.
What is the name for the portion of a star's life cycle when it is using hydrogen for fuel?
main sequence
Is it true that an average star spends 90 percent of its life as a helium burning main sequence star?
no, as a hydrogen burning main sequence star.
What are the main sequence stars life?
Understand that the Main Sequence is not a place or a category that a star belongs to all its life. A star's destiny is controlled by its size and this determines how much time it spends on the Main Sequence.
Will a star spend most of its life as a protostar?
No, it will spend most of it's life as a main sequence star.
What is the step after main sequence in a stars life?
After the main sequence, a star becomes a red giant.
What is a stable stage in the life cycle of a star?
The "main sequence".
Which property of a main-sequence star gradually decreases throughout the star's life?
Mass of hydrogen

Which step in a star's life cycle takes the longest?
Main sequence
Where does a star spend most of its life on an hr diagram?
On the main sequence.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
Is Vega on the main sequence?
Vega is a main sequence star. About half way through it's life, but evolving rapidly.
When a main sequence star has the fuel in its core it becomes?
The next step in its life is to become a "red giant" star.
