What comes after the main sequence stage?
red giant
Which part of the main sequence in the HR diagram contains the stars that took the longest to reach the main sequence?
The HR diagram does not reference stars on their way to the main sequence, only during or after.
How old is the sun and what stage is it in?
The Main Sequence. Stars spend about 90% of their lives in the main sequence, where they fuse hydrogen atoms into helium, through the process of nuclear fusion, to produce energy.
Is the sun a low mass or high mass star and which stage is it in?
The Sun is a medium mass star in main sequence.
What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
What occurs that causes a main sequence star to lose its equilibrium and move on to the next stage in its evolution?
This happens when a main sequence star uses up all of its fuel and swells. Next stage: Red Giant.
During which stage do stars produce energy from the fusion of hydrogen into helium?
Main Sequence
Where is the sun in its main sequence stage?
its to the right of the middle of the main sequence.
What process do stars undergo during the main-sequence stage of their life cycle?
hydrogen fusion
What stage is Sirius a in?
main sequence
What comes after the main sequence stage?
red giant
What is your sun stage in?
Our Sun is in the hydrogen fusion cycle of an average, mid-size, main sequence star. I have no idea what state YOUR Sun happens to be in.
What makes a fusion stop in the main sequence stage?
A star falls of the main sequence when it has exhausted it's supply of hydrogen.
How does the protostar stage of a star's life cycle compare with the main-sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
How does the protostar stage of a stars life cycle compare with the main sequence stage?
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
What is the present stage in the life of the sun?
The Main Sequence stage.
What is one force that is responsible for maintaining the balance of a star during the main sequence stage?
Hydrostatic equilibrium [See related question]
