Accretion Disk Binary System

NASA APOD
COSMIC MESSAGE

Most stars are not alone like our Sun, but exist in binary or multiple systems. In this diagram, a compact star, either a white dwarf, neutron star, or black hole, pulls gas from a nearby blue giant. This creates an accretion disk of material spiraling into the compact object.
