On a polar nova Cygni 1975 (V1500 Cyg).
Abstract
Einstein X-ray observations of Nova Cygni 1975 (V1500 Cyg) are reported, including the discovery that this system is a polar. It is suggested that AM Her-type systems (polars) and DQ Her-type systems (intermediate polars) are the extremes of a continuum of magnetic binaries. Such objects as BG CMi, EX Hya and V1500 Cyg and possibly TV Col, AE Aqr, and CP Pup, whose appearance depends on individual properties and geometry, are intermediate between the two classes.
