论文摘要
共生星是强烈的相互作用的二进制物，由白色矮人和凉爽的巨型组成，主要是光谱M。Draconis属于M. Ag Draconis，属于较少的黄色共生系统，因为该二进制中的凉爽成分比K4早于光谱类型。最近，经过七年的静止，这位共生恒星表现出非常不寻常的活跃阶段，观察到了四个小爆发。得益于业余天文学家和专业观测者的极好参与，我们可以在前所未有的细节中研究Ag Draconis的活动。在目前的工作中，我们讨论了整个共生星体中这种相互作用系统的活动和特殊性，这些星星最近在我们的新在线共生变量数据库中介绍了这些属性。
Symbiotic stars are strongly interacting binaries, consisting of a white dwarf and a cool giant, mainly of spectral type M. AG Draconis belongs to a less numerous group of the yellow symbiotic systems, as the cool component in this binary is of a spectral type earlier than K4. Recently, after seven years of quiescence, this symbiotic star exhibited a very unusual active stage with the four minor outbursts observed. Thanks to the excellent involvement of amateur astronomers and professional observatories, we can study the activity of AG Draconis in unprecedented details. In the present work, we discuss the activity and peculiarities of this interacting system within the entire group of symbiotic stars whose properties have recently been presented in our New Online Database of Symbiotic Variables.
