A contact binary star occurs when two stars are close enough that their outer layers are in contact with each other. Often this can occur when one member of a close binary system enters a red giant stage and swells to the point where it is in contact with the companion star. Such systems can create novae, and perhaps supernovae.

Imagine two stars orbiting each other as they age. Toward the end of their lives their surfaces and atmospheres will grow and begin to merge into a common envelope. Explore how the age and gravitational potential of the system changes the shapes of the stars. You can explore the shape of the merged system by using the gravitational potential control which ignores the individual identities of
