the definition is a sun the is colder than usual and has low mass
The sun is a low mass sequence star. It is classified as a G-type main-sequence star, which means it is in the middle of its stellar evolution and will remain stable for billions of years.
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.
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.
The Sun is a medium mass star in main sequence.

Mass generally increases along the main sequence from low-mass stars like red dwarfs to high-mass stars like blue giants. This means that stars that are more massive are typically hotter, larger, and brighter than low-mass stars. Mass is a key factor that determines a star's temperature, luminosity, and lifetime.
No. Only massive stars can become supergiants.
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 lower right part of the main sequence in the Hertzsprung-Russell diagram contains the stars that took the longest to reach the main sequence. These stars are low mass and cool, so they undergo a longer contraction phase before they start fusing hydrogen in their cores and settle onto the main sequence.
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.
