Determining wither it is a high or low mass star.
The sun is a main sequence star
No. A star's class on the main sequence is ultimately predetermined by its mass, so a star cannot change its position on the main sequence. Epsilon Eridani is about 82% the mass of the sun, which limits it to a lower rate of fusion and thus a lower temperature and luminosity than a G-type star like the sun. Epsilon Eridani's only change in class will come when it leaves the main sequence to become a red giant.
Most of the stars in the universe are found on the main sequence. Stars fall off the main sequence when they begin to die.
Of the stars you can see from Earth, 90% are in the main sequence.
Because it is on the main sequence. [See related question]
No. Stars are only in the main sequence when they are fusing hydrogen.
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.
Stars don't "lose" their "main sequence", because it's not something a star can "have" in the first place.Stars are more properly described as being "on" or "off" the "main sequence", and "sequence" isn't a good word for it anyway, because it implies that there is an actual sequence of events involved; in fact, the normal life sequence of a star has it going off the main "sequence".It may help if you stop thinking of them as "main sequence" stars and start thinking of them as either dwarfs or type III stars.
Main Sequence
The sun is a main sequence star
its to the right of the middle of the main sequence.
There are billions of stars that are not on the main sequence.
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.

Main sequence stars do not really exist - well they do, but read on. Main sequence is a stage in a stars life - where it converts hydrogen into energy, not a particular star or type of star. All stars go through a main sequence, from the smallest to the largest.However, in general, the larger the star, the faster it will burn off it's fuel.
