Answer 1

Answer:

They account for the bulk of the Milky Way’s stellar population, though they are very dim. If red dwarfs are more massive than 0.35 solar masses, they convert hydrogen into helium both in their core and throughout. Because of this, the nuclear fusion process is slowed down and even prolonged. They live for so long that no red dwarf has reached an advanced stage of evolution since the Universe was created. Some examples are: Proxima Centauri, Trappist-1.

Giants and Supergiants

When a star runs out of hydrogen it begins to burn its helium thus it transforms into either a giant or supergiant star. Its core collapses and it gets hotter, resulting in the outer layer to expand outwards. Stars that are either low or medium in mass evolved into red giants. Stars with high-mass, around 10+ times bigger than the Sun, become red supergiants.

During periods of slow fusion, the star can contract itself and become a blue supergiant. This color is usually present when temperatures are spread over a small surface area, making them hotter. Oscillations between red and blue can also occur.
