Even the largest red dwarfs (for example HD 179930, HIP 12961 and Lacaille 8760) have only about 10% of the Sun's luminosity. In general, red dwarfs less than 0.35 M â transport energy from the core to the surface by convection.ed 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 easily be observed. From Earth, not one is visible to the naked eye.
Black dwarfs should not be confused with brown dwarfs, which are formed when gas contracts to form a star, but does not possess enough mass to initiate and sustain hydrogen nuclear fusion. Brown dwarfs were at times called black dwarfs in the 1960s. Neither should black dwarfs be confused with black holes or neutron stars, as neither is the result of the cooling of a white dwarf. Both black dwarfs and white dwarfs are degenerate dwarfs.
