Abstract

New photometric and spectroscopic observations of the nova-like variable V795 Her are reported. A period of 0.1164865(4) days for the light curve variation, and a 0.1082648(3) day period with an amplitude of 70 + or - 20 km/s for the radial velocity variation were established, which leads to the conclusion that the photometric and spectroscopic periods are different. It is argued that V795 Her is an intermediate polar and that one period is the orbital, identified as spectroscopic, and the other is associated with the rotation of the magnetized, accreting white dwarf. It is suggested that the photometric period is the beat period between the orbital period and the rotation period of the white dwarf. The orbital period of V795 Her is near the middle of the gap in the orbital period distribution for cataclysmic variables. Two possibilities for the evolutionary state of V795 Her are examined. 33 refs.
