摘要:

我们用光学方法鉴别了最近发现的一个积分源IGR J 08390 - 4833,它有一个激变变星,即双星系统中的吸积白矮星。光谱显示出上升的蓝色连续谱,以及Balmer和HeII发射线。对光源的光变曲线的分析表明,在一个小时的时间尺度上存在明显的内在变化,尽管我们并不认为这种变化是周期性的。因此,我们还不能将对象分类到特定的CV子类中。

英文摘要:

We have optically identified a recently discovered INTEGRAL source, IGR J08390--4833, with a cataclysmic variable, i.e. an accreting white dwarf in a binary system. The spectrum exhibits a rising blue continuum together with Balmer and HeII emission lines. Analysis of the light curve of the source shows clear presence of intrinsic variability on a time scale of the order of an hour, although we do not claim that this variability is periodic. Therefore we are not yet able to classify the object into a specific CV subclass.
