A dwarf star is a star of relatively small size and low luminosity. 1  Most main sequence stars are dwarf stars. The term was originally coined in 1906 when the Danish astronomer Ejnar Hertzsprung noticed that the reddest starsâclassified as K and M in the Harvard scheme could be divided into two distinct groups.
neutron star - a star that has collapsed under its own gravity; it is composed of neutrons. nova - a star that ejects some of its material in the form of a cloud and become more luminous in the process. red dwarf, red dwarf star - a small, old, relatively cool star; approximately 100 times the mass of Jupiter.
