Astrophysical parameters of ten poorly studied open star clusters

Abstract We present the fundamental parameters of ten open star clusters, nominated from Kronberger et al. who presented some newly discovered stellar groups on the basis of the Two Micron All Sky Survey photometry and Digitized Sky Survey visual images. Star counts and photometric parameters (radius, membership, distance, color excess, age, luminosity function, mass function, total mass, and dynamical relaxation time) have been determined for these ten clusters for the first time. In order to calibrate our procedures, the main parameters (distance, age, and color excess) have been reestimated for another five clusters, which are also studied by Kronberger et al.


Keywords Galaxy: open clusters and associations: general — stars: luminosity func- tion, mass function — catalogs, surveys — infrared: stars
