OSO-8 x-ray observations of AM Hersoulis
Description
Hard X-ray observations of the binary system AM Her were coincident with soft X-ray and ground-based optical measurements. In the 2--60 keV band, variability was detected with an eclipse during phases 0.5 to 0.7 with respect to the 0. d 12892 period optical minima, synchronous with the known soft X-ray eclipse. The 2--60 keV uneclipsed flux was 9.5 x 10 -10 erg sq cm/sec, of which 86% lies above 10 keV. Thus AM Her contains a hard source located near the similarly eclipsed soft X-ray source. The X-ray data are interpreted in terms of thermal bremsstrahlung from accretion onto a white dwarf
