QPOs in CVs: An executive summary
摘要:
概述了激变变星中观测到的各种准周期光度调制的性质。这两种主要类型,在CV文献中称为矮新星振荡和准周期振荡,与X射线双星中的高频和低频准周期振荡有相似之处。还有一个被观测到的更长周期的矮新星振荡。在CV中,观察到的这些振荡之间的相互关系表明,一个模型的磁控吸积到一个快速旋转的赤道带的吸积气体。在某些系统中观察到中心白矮星的非径向振荡。
英文摘要:
An overview is given of the properties of the various kinds of quasi-periodic luminosity modulations observed in cataclysmic variables (CVs). The two principal types, known in the CV literature as dwarf nova oscillations and quasi-periodic oscillations, have similarities to the high and low frequency quasi-periodic oscillations in X-Ray binaries. There is a further well observed class known as longer period dwarf nova oscillations. In CVs the observed interrelations between these oscillations suggests a model of magnetically controlled accretion onto a rapidly rotating equatorial belt of accreted gas. Non-radial oscillations of the central white dwarf are observed in some systems.
