SYMBIOTIC STARS

Objects: #3404 CH Cygni

UW Astronomer: Chris Anderson


Symbiotic stars are star systems where the stars have radically different temperatures. The stars are believed to be in pairs in which gas from a large, cool star falls onto a smaller, invisible companion. Symbiotic stars are of interest to WUPPE because they show polarization which could provide information on the geometry of the star system. WUPPE researchers will be testing the theory that UV polarization will result from the scattering of photons by the streams of gas in the system.
