中文摘要
在之前的一项研究中,远离银河系平面的激变变星被发现其性质与靠近银河系平面的变星不同。将获得这些天体的光谱和光度,以研究它们的双星伴星的性质。这将允许获得距离,并从它们获得引起变星爆发的吸积盘的亮度。将对这些天体的银河系平面对应物进行搜索。我们将探讨这些系统与关于突变变量冬眠的理论之间的关系。
英文摘要
In a previous study, cataclysmic variables located far from the galactic plane were found to differ in their properties from those near the plane. Spectra and photometry of such objects will be obtained to study the nature of their binary companions. This will allow the distances to be obtained and from them, luminosities of the accretion disks which give rise to the outbursts of the variables. A search for galactic plane counterparts of these objects will be made. The relationship of these systems to theories regarding the hibernation of cataclysmic variables will be explored.
