【摘要】 激变变星是密近双星系统,包含一颗白矮星主星和一颗晚型星伴星。晚型星伴星充满了其Roche瓣,并向主星转移物质,在主星周围形成一个吸积盘。这类双星对于我们认识吸积过程、密近双星的演化等是相当重要的。本文主要从实测角度综述激变变星研究的现状,并讨论一些尚待解决的问题。更多还原

【Abstract】 The cataclysmic variable is a close binary system, in which a low-mass, late-type secondary star fills its Roche lobe and is transferring its mass to a white dwarf primary star. In most of these systems the transferred mass forms an accretion disk around the primary star. Cataclysmic variables are important objects to our understanding accretion processes,evolution of close binaries,and other interesting issues. In the present paper a summary of observational researches on cataclysmic variables is given and a few unsolved problems are discussed as well.更多还原
