The simplest way to get a cluster’s parameters in the Gaia era (Dolidze 41)

Ashraf Latif Tadross

Abstract

The astro-photometric parameters of the open star cluster Dolidze 41, which is located in the constellation Cygnus, have been investigated using the Gaia DR2 large survey that is merged with the near infrared Two Micron All Sky Survey (2MASS) database. The radial density distribution (limited, core and tidal radii), color-magnitude diagrams, galactocentric coordinates, distances, color excess and age of Dolidze 41 are presented. The Gaia DR2 astrometry helped us to define the membership of the cluster stars easily. The luminosity and mass functions, the entire luminosity and mass, and the relaxation time of the cluster have been estimated as well.
