论文摘要
积分白矮人（WDS）构成了积分天文台检测到的硬X射线源的显着部分。它们中的大多数是中间极性（IP）和极性类型的磁性灾难变量（CVS），但是Nova-Likes系统和具有光学较薄边界层，矮novae（DNS）和共生二进制（或共生星（或共生星，Syss，syss）的贡献也不是均无原形的。在这里，我们简要回顾了从灾难性变量和通过积分分类的共生二进制的观察结果获得的结果。突出显示的结果包括已知的IP群体的显着增加，大部分IPS的WD质量的确定，磁性CVS的发光函数的建立以及揭示了银河脊X射线发射的起源，这似乎与磁性CVS的硬发射很大程度上相关。
Accreting white dwarfs (WDs) constitute a significant fraction of the hard X-ray sources detected by the INTEGRAL observatory. Most of them are magnetic Cataclysmic Variables (CVs) of the intermediate polar (IP) and polar types, but the contribution of the Nova-likes systems and the systems with optically thin boundary layers, Dwarf Novae (DNs) and Symbiotic Binaries (or Symbiotic Stars, SySs) in quiescence is also not negligible. Here we present a short review of the results obtained from the observations of cataclysmic variables and symbiotic binaries by INTEGRAL. The highlight results include the significant increase of the known IP population, determination of the WD mass for a significant fraction of IPs, the establishment of the luminosity function of magnetic CVs, and uncovering origin of the Galactic ridge X-ray emission which appears to largely be associated with hard emission from magnetic CVs.
