Photometric and kinematical analysis of Koposov 12 and Koposov 43 open clusters

W. H. Elsanhoury

We present a photometric and kinematical analysis of two and poorly studied open clusters; Koposov 12 (FSR 802) and Koposov 43 (FSR 848) by using cross-matched data from PPMXL and…

An investigation of open cluster Melotte 72 using Gaia DR2

Yasser Hendy, Ashraf Tadross

The estimation of the main parameters of star clusters is significant in astrophysical studies. The most important aspect of using the Gaia DR2 survey lies in the positions, parall…
