摘要:

介绍了2004-2014年期间UBVRI对前主序星V350 Cep的光学光度观测结果。这颗恒星于1977年被发现,由于它的亮度显著增加超过5等(R)。在以往的研究中,V350 Cep被认为是一个潜在的FUor或EXor出疹变量。我们的数据表明,在观测期间,恒星保持其最大亮度与低幅度光度变化。我们的结论是,V350 Cep可能是介于FUors和EXors之间的中间天体,类似于V1647 Ori。

英文摘要:

Results from UBVRI optical photometric observations of the pre-main sequence star V350 Cep during the period 2004-2014 are presented. The star was discovered in 1977 due to its remarkable increase in brightness by more than 5 mag (R). In previous studies, V350 Cep was considered a to be a potential FUor or EXor eruptive variables. Our data suggest that during the period of observations the star maintains its maximum brightness with low amplitude photometric variations. Our conclusion is that V350 Cep was probably an intermediate object between FUors and EXors, similar to V1647 Ori.
