WebRed dwarfs are small (0.08-0.5 M⊙ ), low-surface temperature (2500-4000 K) Main Sequence stars with a spectral type of K or M. It is their low temperature which dictates their red appearance. Their small diameter (typically a few tenths that of the Sun) means that they are also faint. WebA white dwarf is one of the densest objects in the entire solar system, the only object that possesses a greater density is a neutron star.
