论文摘要
本文报告是由于2007年2月至2020年1月在该期间收集的三个可变预序列星的第一个长期BV（RI）C光度CCD观察结果。研究的恒星位于Cepheus OB3协会内PMS明星V733 CEP领域。我们研究的所有恒星都显示出全光线带的快速光度变异性。在本文中，我们描述并讨论了这些恒星的光度法及其可变性的可能原因。在两个恒星的光变化中，我们发现了周期性。
This paper report results from the first long-term BV(RI)c photometric CCD observations of three variable pre-main-sequence stars collected during the period from February 2007 to January 2020. The investigated stars are located in the field of the PMS star V733 Cep within the Cepheus OB3 association. All stars from our study show rapid photometric variability in all-optical passbands. In this paper, we describe and discuss the photometric behavior of these stars and the possible reasons for their variability. In the light variation of two of the stars we found periodicity.
