The 1982 eclipse of 31 Cygni.
Abstract
UBV photometry and optical-UV spectroscopy of the primary eclipse of the long period ζ Aurigae-like system 31 Cygni are reported. The precise timings made possible by the photometry imply that the spectral features could be due to an accretion shock associated with a hot star embedded in an extended chromosphere surrounding the red supergiant. The data also suggest an extended clumpy structure to the atmosphere of the late-type supergiant in the binary.
