QZ aur (QZ Auriga)

An Eclipsing Cataclysmic Variable Star

QZ Aur is an eclipsing binary star in the constellation Auriga. It is a cataclysmic variable system consisting of a white dwarf and a companion star. Matter from the donor star flows onto the white dwarf, forming an accretion disk. The system experiences outbursts caused by thermonuclear explosions on the white dwarf's surface. QZ Aur is observed as a classical nova, with sudden increases in brightness. It is of interest for studying the evolution of close binary systems.
