Variable, optically thick plasma in the interacting binaries R Arae and HD 207739

Attention is given to observational evidence for the presence of variable and optically thick extrastellar gas in two binary stars, R Arae and HD 207739, which appear to be in the evolutionary phase immediately preceding or following the short lived supercritical mass transfer phase. In both binarie...

Zusammenfassung:	Attention is given to observational evidence for the presence of variable and optically thick extrastellar gas in two binary stars, R Arae and HD 207739, which appear to be in the evolutionary phase immediately preceding or following the short lived supercritical mass transfer phase. In both binaries, spectral lines and energy distributions are variable outside eclipse.
