ASCA Discovery of the New Magnetic Cataclismic Variable AXJ2315-592

Abstract

The new magnetic cataclysmic variable (CV) AX J2315-592 was discovered by ASCA and identified as a new AM Her type object. The light curve shows a clear modulation at the period of 5360sec. The X-ray spectrum is represented by hard thermal bremsstrahlung with negligible absorption and strong iron K emission line, which are typical of magnetic CVs. The large amplitude variation observed in this object are characteristics of AM Her type objects. Modulation amplitude is, however, found to be smaller in higher energies, which is seen in intermediate polars in general. From these X-ray properties, the possible accretion pole geometry is discussed.
