In astronomy, a contact binary is a binary star system whose component stars are so close that they touch each other or have merged to share their gaseous envelopes. A binary system whose stars share an envelope may also be called an overcontact binary.

Spectroscopic observations of 44i Boo and VW Cep by IUE established the presence of high-temperature chromospheric and transition region emission lines in the spectra of these stars. The HEAO 1 and IUE results implied that the processes causing X-ray 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.

Contact binary stars

The uppermost part of the stellar atmospheres forms a common envelope that surrounds both stars. As the friction of the envelope brakes the orbital motion, the stars may eventually merge. W Ursae Majoris is an example. Astronomers have discovered many “contact” binaries — systems where the stars are touching each other. Some of them are known as over-contact binaries.

Close this message to accept … The properties of contact binary stars were studied using the catalogue data. As is well known since Lucy's ([CITE],b) and Mochnacki's ([CITE]) studies, primary components transfer their own energy to the secondary star via the common envelope around the two stars.

This system comprises two stars in a very tight orbit around each other. The stars' atmospheres are in contact, and the friction the contact causes slows the stars' orbits so that eventually they touch, merging into one star. Senior ASP Developer. Orlando, FL.
