Cataclysmic variable stars (CVs) are stars that irregularly increase in brightness by a large factor, then drop back down to a quiescent phase (Warner, 1995). They consist of two component stars: a WD primary and a mass donor star. CVs are usually divided into several types, such as class...
While classed as eruptive variables, these stars do not undergo periodic increases in brightness; instead, they spend most of their time at maximum brightness. At irregular intervals, however, they suddenly fade by 1 - 9 magnitudes, slowly recovering to their maximum brightness over months to year...

This core will suddenly collapse as its electrons are driven into its protons, forming neutrons, neutrinos, and gamma rays in a burst of electron capture and inverse beta decay. The shockwave formed by this sudden collapse causes the rest of the star to explode in a supernova. Supernovae ...
Such an event is called anova—a rapid increase in the brightness of a white dwarf that reignites after years of slumber. These outbursts are different thansupernovae, which are much more dramatic. Supernovae occur when a dying star erupts in a release of ...
