A Study on White Dwarf Masses in Cataclysmic Variables Based on XMM-Newton and Suzaku Observations

Li, Xiang-Dong; Xu, Xiao-Jie; Yu, Zhuo-Li

The distribution of the mass of white dwarfs (WDs) is one of the fundamental questions in the field of cataclysmic variables (CVs). In this work, we make a systematical investigation on the WD masses in two subclass of CVs: intermediate polars (IPs) and non-magnetic CVs in the solar vicinity based on the flux ratios of Fe XXVI-Lyα to Fe XXV-Heα em…
