论文摘要
我们在我们银河系中心的超大质量黑洞Sgra*的超质量黑洞上观察到S-Cluster Star S62。 SGRA*周围S62的轨道时间期为9。9年。我们得出其质量约为2 m_solar，与S-Cluster的其他成员一致。从露西 - 里查森（Lucy-Richardson）的图像中，我们确定了16.1 mag的K波段幅度。我们观察到恒星的几乎两个完整的轨道，其中有两个不同的独立望远镜和三种不同的仪器。 S62到SGRA*在其大约2个MAS的Periapse处的近距离距离导致重力periapse偏移近10％/轨道。
We observe the S-cluster star S62 on its Keplerian orbit around the supermassive black hole in the center of our galaxy, SgrA*. The orbital time period of S62 around SgrA* is 9.9 years. We derive its mass to be around 2 M_solar which is consistent with other members of the S-cluster. From the Lucy-Richardson deconvolved images, we determine a K-band magnitude of 16.1 mag. We observe almost two complete orbits of the star with two different and independent telescopes and three different instruments. The close distance of S62 to SgrA* at its periapse of around 2 mas results in a gravitational periapse shift of almost 10%/orbit.
