论文摘要
恒星簇的主要参数的估计是天体物理研究中非常重要的目标。已知目录中列出的许多开放群集具有不足的星体参数。改进观察结果和分析方法证明了其中一些不是真正的簇。使用Gaia调查的最重要方面是使用均匀光度法为簇星的位置,视差和适当的运动,这使成员资格候选者精确确定。在这方面,已经估计了开放型星团Kronberger 60的几个光度参数。在研究径向密度谱时,发现半径为10.0 +/- 0.5 arcmin。它的距离为1935 +/- 90 pc,年龄为800 +/- 50 MYR。另外,发红,发光度;质量功能和簇的总质量也已估计。我们的研究表明,Kronberger 60的动态放松行为。
The estimation of the main parameters of star clusters is a very important target in astrophysical studies. Many of the open clusters listed in known catalogs have insuffcient astrometric parameters. Improving the observations and analysis methods proved that some of them are not true clusters. The most important aspect of using the Gaia survey lies in the positions, parallax, and proper motions for the cluster stars with the homogeneous photometry, which makes the membership candidates precisely determined. In this respect, several photometric parameters of the open star cluster Kronberger 60 have been estimated. On studying the radial density profile, the radius is found to be 10.0+/-0.5 arcmin. It is located at a distance of 1935+/-90 pc, with an age of 800+/-50 Myr. Also, the reddening, the luminosity; mass functions, and the total mass of the cluster have been estimated as well. Our study is showing a dynamical relaxation behavior of Kronberger 60.
