Evidence of thermal disequilibrium in contact binaries.

KAEHLER H.

Abstract (from CDS):

We present a test which is sufficient to disprove thermal equilibrium in observed contact binaries. The test is applied to a number of systems with good spectroscopic data. All of them are shown to be in thermal imbalance. Accordingly, many (possibly all) contact binaries evolve on a thermal time-scale, probably in thermal cycles as proposed by Lucy (1976) and Flannery (1976).
