The sun is an intermediate-mass star.
Determining wither it is a high or low mass star.
High mass.
High mass adult stars are classified as supergiants or giants, while low mass adult stars are classified as main sequence stars. This classification is based on the mass of the star and where it falls on the Hertzsprung-Russell diagram.
Altair is classified as an A-type main-sequence star, which means it is relatively high-mass compared to other stars like the Sun. Its mass is estimated to be about 1.8 times that of the Sun.
There are more low mass stars. this is for two reasons:- # the star forming process generates more low mass stars # High mass stars burn out very quickly and explode as supernovas and thus over time there are less and less of them.
The Sun is a medium mass star in main sequence.

White dwarf
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
white dwarf
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
As always the case, what we see is not always true.Alpha Cenauri is in fact a triple star system, comparison not surprising a, b, and c stars.A is a normal main sequence star - so not low massB is a normal main sequence star - so not low mass, slightly cooler.C is a red dwarf star - a low mass star
