An Unusual Variable Star Ch-Cygni
Abstract
The existing observational data on CH Cyg agrees well with a model consisting of a semiregular M6 III giant and a white dwarf with a transient accretion disk formed at the time of the large maxima. The model can be tested by means of x-ray and speckle-interferometric observations.
