摘要

AU Monocerotis是一颗被充分研究的相互作用双星，是双周期变星组的成员，其主要特征是存在一个平均持续约33倍轨道周期的长光度周期。利用2008 - 2015年的光谱覆盖，构建了h - α多普勒图。我们发现，在系统的低状态下，吸积盘的活动更活跃，这与HD 170582的情况类似。

On the variability of the accretion disk of AU Monocerotis

AU Monocerotis is a well studied interacting binary star and a member of a group called Double Periodic Variables, whose principal characteristic is the existence of a long photometric cycle lasting on average about 33 times the orbital period. We made use of spectra covering from 2008 to 2015 to construct Hα Doppler maps. We found higher activity in the accretion disk during the low state of the system, similar to that found in HD 170582.
