A dwarf star is a star of relatively small size and low luminosity. 1  Most main sequence stars are dwarf stars.

Dwarf Star. A dwarf star is a star that is not a giant or supergiant â¦ in other words, a dwarf star is a normal star! Of course, some dwarf stars are much smaller (less massive, have a smaller radius, etc) than normal (or main sequence, not really massive) stars â¦ and these have names, like white dwarf, red dwarf, brown dwarf, and black dwarf. Our very own Sol (the Sun) is a dwarf star â¦ a yellow dwarf.
