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 trueclusters. 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, theluminosity 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.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
