A white dwarf star is the final evolutionary phase of a star, occurring after low- and medium-mass stars lose the necessary mass to support carbon-fusing temperatures. Prior to becoming a white dwarf, a star becomes a re... More »

A blue dwarf is a hypothetical star that is created from a red dwarf star that has exhausted most of its hydrogen fuel supply. Red dwarf stars fuse hydrogen very slowly, and they can allow a large amount of their hydroge... More »

A black dwarf star is a white dwarf star that has cooled down to the same temperature as the cosmic microwave background. The cosmic microwave background is the thermal radiation left over from the Big Bang or the temper... More »

According to the University of Leicester, high mass stars are those that have at least three times the mass of the Sun. By contrast, low mass stars have less than half of the mass of the Sun, and intermediate mass stars ... More »

An average star is a star predicted or observed to go through the main sequence life cycle: nebula to main sequence star to red giant to white dwarf to black dwarf. Stars with more mass explode into a supernova and colla... More »

A white dwarf is a star at the end of its life cycle that can no longer fuse carbon due to insufficient mass and temperature. It may also be referred to as a degenerate dwarf. More »

Main sequence stars are stars in the phase where they are fusing hydrogen atoms to form helium. Once a star runs out of hydrogen and starts fusing helium to form heavier elements, a star enters its dying phase. More »
