“墨西哥湾”区5颗前主序星的长期BVRI光变曲线
Long-term BVRI light curves of 5 pre-main sequence stars in the field of "Gulf of Mexico"
摘要：
我们提供了2013年4月至2014年7月期间五颗PMS星的BVRI光度观测的新数据。这些恒星位于NGC 7000/IC 5070（墨西哥湾）的区域，这是一个恒星形成活跃的区域。本文是我们对这一区域年轻天体长期测光研究的继续。PMS星的长期光度观测对它们的准确分类是非常重要的。我们的研究结果表明，所研究的恒星在所有波段表现出不同类型的光度变化。我们试图用我们的长期测光数据和其他作者发表的数据对它们进行分类。
英文摘要：
We present new data from BVRI photometric observations of five PMS stars during the period from April 2013 to July 2014. The stars are located in the field of NGC 7000/IC 5070 ("Gulf of Mexico") - a region with active star formation. The presented paper is a continuation of our long-term photometric investigations of the young stellar objects in this region. The long-term multicolor photometric observations of PMS stars are very important for their exact classification. Our results show that the studied stars exhibit different types of photometric variability in all bands. We tried to classify them using our data from the long-term photometry and data published by other authors.
