Answer: The radius of a white dwarf is determined by a balance between the inward force of gravity and the outward push of "electron degeneracy pressure."
A(n) "nova" occurs when hydrogen fusion ignites on the surface of a white dwarf in a binary system.
A(n) "massive star supernova" occurs when fusion creates iron in the core of a star.
A white dwarf in a close binary system will explode as a supernova if it gains enough mass to exceed the "white dwarf limit (1.4 solar masses)".
A(n) "accretion disk" consists of hot, swirling gas captured by a white dwarf (or neutron star or black hole) from a binary companion star.
A(n) "white dwarf supernova" can occur only in a binary system, and all such events are thought to have the same luminosity.
