论文摘要
我们介绍了V565 Mon Pre-Main序列星的详细光谱研究，这是Parsamian 17 Cometary Nebula的照明之星。 2018年2月15日，在Byurakan天体天文台中用2.6 M望远镜进行观测。径向速度和同等宽度是V565 MON的最突出线。我们构建了光谱能分布并估计恒星的主要参数，例如，V565 MON的辐射光度为$ L_ {V565} \ oft 130L _ {\ odot} $。考虑到V565 Mon的所有特征，我们得出结论，这位年轻的中间质量恒星可以属于T Tau和Haebe Star之间的某些中级阶层。对于年轻恒星来说，非常不寻常的是光谱中存在强吸收BA II系。讨论了有关此问题的可能解释。因此，我们认为V565 Mon是一个独特的例子，可以帮助理解年轻恒星中核合成问题中的一些开放问题。
We present the detailed spectroscopic study of V565 Mon pre-main-sequence star, which is the illuminating star of Parsamian 17 cometary nebula. Observations were performed with 2.6 m telescope in Byurakan Astrophysical Observatory in 15 February 2018. Radial velocities and equivalent widths of the most prominent lines of V565 Mon are presented. We built the spectral energy distribution and estimated the main parameters of the star, for example obtained bolometric luminosity of V565 Mon is $L_{V565}\approx 130L_{\odot} $ . Considering all features of V565 Mon we came to conclusion that this young intermediate-mass star can belongs to some intermediate class between T Tau and HAeBe stars. Very unusual for a young star is the presence of strong absorption Ba II lines in the spectrum. Possible explanations on this issue are discussed. Hence, we think that V565 Mon is a unique example, which can help to understand some open questions in nucleosynthesis problem in young stars.
