the definition is a sun the is colder than usual and has low mass
Main Sequence Stars
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.
Determining wither it is a high or low mass star.
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.
No. Only massive stars can become supergiants.
Main Sequence Stars
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.

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

A star with a low mass will go through these stages: 1. Protostar nebula 2. Main sequence (as a red dwarf) 3. Red giant 4. Planetary nebula 5. White dwarf (6. Black dwarf is theorized to occur after white dwarf)
The sun is an intermediate-mass star.
No. A white dwarf is the collapsed remnant of the core of a low to medium mass star. It has a mass comparable to that of a star, but is about the size of a small planet.
Yes, that's correct, for a "low mass" star like our Sun. Smaller stars, with about 8% to 80% of the Sun's mass, are red dwarfs. They follow the same sequence, but without the red giant stage.
