White dwarf is a degenerate dwarf or a stellar core ramnant mainly composed with electron degenerate matter.
White dwarf is very massive. Its mass is just like with the mass of sun but the volume is just like with earth.
White dwarf is luminous. The luminousity comes from the emission of thermal radiation from white dwarf. The thermal energy stored into white dwarf is radiate as thermal radiation.
White dwarf is a final evolutionary state of stars. Its mass is not enough sufficient to form a neutron star.
Though, in white dwarf mass is convert into energy there no fusion take place within white dwarf.
