1H1752+081: AN "INTERMEDIATE" SYSTEM BETWEEN POLAR AND INTERMEDIATE POLAR ?
ABSTRACT
Polar and Intermediate Polar have been recognized as the subclasses of Magnetic Cataclysmic Variables. They are, however, considerably different with each other on various aspects, such as mechanical properties and emission spectral components etc. It is suggested from optical observations that 1H1752+081 is truely an "intermediate" system between Polar and Intermediate Polar. We propose 60ksec observation of 1H1752+081 in order to (1) measure the rotational period of the white dwarf, (2) detect the soft blackbody component, and (3) measure the mass of the white dwarf. This observation enables us to investigate relation between Polar and Intermediate Polar for the first time at the hard X-ray bandpass.
