Dwarf Star

Originally put forward by Ejnar Hertzsprung in the early years of the 20th century, the term dwarf star has come to be applied to any star on the main sequence, for example, the Sun is regarded as a yellow dwarf star. The term has been extended to other stars that are not on the main sequence such as white dwarfs and brown dwarfs.A brown dwarf is an gaseous object that is larger than jupiter but less than 1% of the mass of the Sun. It emits energy feebly as it can convert hydrogen into duterium but can go no further as it’s mass is too low.

The term ‘Red Dwarf’ was used as the title to the highly successful and immensely funny TV comedy by Naylor and Grant; the eponymous Red Dwarf was a space mining ship.

 

Black Dwarf

A dead star, which has used up all its reserves of energy. The ultimate fate of a White Dwarf. It is therefore a small, cold star.
