Characteristics of the open star cluster Kronberger 60 using Gaia DR2

Abstract

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±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 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.
