This artist's conception shows a binary star system that produces recurrent novae, and ultimately, the supernova PTF 11kx. A red giant star (foreground) loses some of its outer layers though a stellar wind, and some of it forms a disk around a companion white dwarf star. ... When the mass builds up to the near the ultimate limit a white dwarf star can take, it explodes as a type Ia supernova, destroying the white dwarf. ...
