XMM-牛顿时代磁激变变星的X射线发射

The X-ray emission of magnetic cataclysmic variables in the XMM-Newton era

M. Mouchet, J. M. Bonnet-Bidaud, D. de Martino

摘要:

本文综述了近十年来由XMM-Newton、Chandra和Suzaku大型X射线天文台观测得到的磁激变双星的X射线光谱特性。我们重点讨论了根据主要物理参数(磁场、局域吸积率和白矮星质量)预测的不同吸积模式的特征。所观察到的光谱行为的多样性表明,在中间极和极的参数值范围很广,在这两个类之间的可能的进化联系。

英文摘要:

We review the X-ray spectral properties of magnetic cataclysmic binaries derived from observations obtained during the last decade with the large X-ray observatories XMM-Newton, Chandra and Suzaku. We focus on the signatures of the different accretion modes which are predicted according to the values of the main physical parameters (magnetic field, local accretion rate and white dwarf mass). The observed large diversity of spectral behaviors indicates a wide range of parameter values in both intermediate polars and polars, in line with a possible evolutionary link between both classes.
