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 insufficient astrometric parameters. Improving the observations and analysis methods proved that some of them are asterisms and not true clusters. The most important aspect of using the GAIA DR2 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 astor-photometric parameters of the open star cluster Kronberger 60 have been estimated. On studying the radial density profile, the radius is found to be \(10.0\pm 0.5\) arcmin. It is located at a distance of \(1935\pm 90\) pc, with an age of \(800\pm 50\) Myr. Also, the reddening, the luminosity and mass functions, and the total mass of the cluster have been estimated as well. Our study shows a dynamical relaxation behavior of Kronberger 60.

使用Gaia DR2的开放星团Kronberger 60的特征

恒星团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星团的天体参数不足。改进观测和分析方法证明了其中一些是星号,而不是真正的星团。使用GAIA DR2测量最重要的方面在于均质光度法对星团星的位置,视差和适当运动的影响,这使得精确确定成员资格成为可能。在这方面,已经估计了恒星团Kronberger 60的几个Astor光度参数。在研究径向密度分布时,发现半径为\(10.0 \ pm 0.5 \) arcmin。它位于\(1935 \ pm 90 \)的距离处pc,年龄为\(800 \ pm 50 \)马币。另外,还估计了团簇的变红,发光度和质量函数以及总质量。我们的研究显示了Kronberger 60的动力学松弛行为。
