It uses up most of the hydrogen it started with.
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.
The Sun is a medium mass star in main sequence.
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
The Sun is a medium mass star on the main sequence.
its to the right of the middle of the main sequence.
main sequence
A star falls of the main sequence when it has exhausted it's supply of hydrogen.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.

Main Sequence
The main sequence stage is a point in the stellar evolution of stars in the universe at which every star converts hydrogen into helium in its cores and releases huge amounts of energy.
