WebThese remnant stars lie in a band that stretches diagonally across the HR diagram below the main sequence. They are at their most-luminous blue when young, but they become dimmer and redder as they cool. Degenerate dwarfs are supported by degeneracy pressure, so their size does not change. WebA red dwarf is the smallest and coolest kind of star on the main sequence.Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.From Earth, not one star that fits the stricter definitions of a red dwarf is visible to the naked eye.

Their outer layers of gas expand and cool; therefore, the stars move to the right on the H-R diagram. Although a star cools when it becomes a red giant, it grows so large its luminosity (or total power emitted) increases.
