论文摘要
在本文中，报道了预先序列星V1180 CA的光学光度观察结果。恒星是与乌云林德斯1340相关的年轻变量，该变量位于卡西奥佩亚（Cassiopeia）恒星形成区域的太阳距离为600 pc。 V1180 CAS显示出较大的振幅变异性，该变异性解释为吸积诱导和消灭驱动效应的组合。从2011年9月至2022年2月收集了来自VRI CCD光度观测值的数据。在监视过程中，我们记录了几次亮度下降，幅度较大，最高为5 mag。 （i带）。同时，还记录了几周内亮度的提高。在本文中，我们比较了V1180 CAS获得的光度数据与对其他低质量预序序列对象的观察。
In this paper results from the optical photometric observations of the pre-main-sequence star V1180 Cas are reported. The star is a young variable associated with the dark cloud Lynds 1340, located at a distance of 600 pc from the Sun in the star forming region in Cassiopeia. V1180 Cas shows a large amplitude variability interpreted as a combination of accretion-induced and extinction-driven effects. Our data from VRI CCD photometric observations of the star are collected from September 2011 to February 2022. During our monitoring, we recorded several brightness dips with large amplitudes of up to 5 mag. (I-band). At the same time, increases in brightness over periods of several weeks have also been recorded. In this paper, we compare the photometric data obtained for V1180 Cas with observations of other low-mass pre-main sequence objects.
