Binary Stars

Most stars are in multiple systems. It has been estimated that more than half of all of the stars in the sky are orbited by companion stars. In some cases these stars are close enough to have drastic effects on each other's life history.

Imagine the Universe is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA's Goddard Space Flight Center.
