密近双星

在密近双星系统HerX-1/HzHer中，HerX-1的X射线辐射对HzHer大气的加热效应，使大气结构变得很复杂。

In close binary system Her X-1 / HZ Her , the structure of HZ Her atmosphere is complicated due to X-ray heating .

密近双星轨道周期的准周期／不规则变化（典型的相对变化幅度为△P／P-10-7-10-5）也只能用磁活动来解释。

Quasi-periodic / irregular orbital period variations ( with typical relative amplitude of △ P / P - 10-7 - 10-5 ) can be only explained by magnetic activity .

自从1976年，Hall明确地提出RsCVn型双星的定义以来，密近双星的类太阳活动（也叫色球活动或磁活动）性质就引起众多天文工作者的极大兴趣。

Since RS CVn-type binary was defined by Hall in 1976 , the solar-type activity (" chromospheric activity " or " magnetic activity ") of contact binaries interests many astronomic researchers .

在密近双星系统HerX-1/HzHer中，HerX-1被HzHer掩食时的X射线光度变化，为研究HzHer的大气结构，提供了一个直接的观测证据。

In close binary system Her X-I / HZ Her , the gradual occultations of the X-ray pulsar Her X-1 by its companion HZ Her offer a direct observational evidence of the atmospheric structure of HZ Her .

该模型认为，密近双星中的两子星靠得近，存在微小的磁力。因为活动子星的磁场是变化的，因此子星间的磁力和系统的轨道周期也发生了微小的变化。

In the model , there is weak magnetic force between two component stars as result of small separation . As the magnetic fields are varying , the magnetic force and the orbital period also show variations .
