论文摘要
闪烁是在所有积极系统中都观察到的快速变异性。已经表明，在大多数灾难性变量中，闪烁的变量起源于积聚盘。然而，在极力杆中，白色矮人的强磁场阻止了积聚盘的形成。因此，在极点闪烁的起源尚不清楚。我们分析了在七个极点中使用轨道相闪烁幅度的变化，以揭示其原产地点。我们表明，至少在某些方面，有两个独立的闪烁来源。此外，至少有一个来源位于距系统主要光源较大距离的位置。
Flickering is a fast variability observed in all accreting systems. It has been shown that in most cataclysmic variables flickering originates in the accretion disc. However, in polars the strong magnetic field of the white dwarf prevents the formation of an accretion disc. Therefore, the origin of flickering in polars is not clear. We analyzed the changes of flickering amplitude with orbital phase in seven polars in order to reveal its site of origin. We show that at least in some polars there are two separate sources of flickering. Moreover, at least one of the sources is located at a large distance from the main source of light in the system.
