RXTE broadband X-ray spectra of intermediate polars and white dwarf mass estimates

Abstract

We present results of an analysis of broadband spectra of 14 intermediate polars obtained with the RXTE observatory (PCA and HEXTE spectrometers, 3-100 keV). By means of our calculations of the structure and the emergent spectrum of the post-shock region of intermediate polars we fitted the observed spectra and obtained estimates of the white dwarf masses. The estimated masses are compared with masses obtained by other authors.
