Sun B5 (White Dwarf)

This small white star is largely made up of degenerate matter and is slowly cooling, having ceased thermonuclear fusion after exhausting its fuel. The temperature of these stars is generally uniform through the body due to the excellent thermal conduction of degenerate electrons making up the bulk of their mass.

High surface gravity leads to separation and purification of elements in these stars such that, while generally composed mostly of carbon and oxygen, the atmosphere is rich in lighter elements.
