Memberships and CM diagrams of the open cluster NGC 7243
Abstract
The results of astrometric and photometric investigations of the open cluster NGC 7243 are presented. Proper motions of 2165 stars with root-mean-square error of 1.1;mas yr-1 were obtained by means of PDS scanning of astrometric plates covering 97 years. A total of 211 cluster members down to V=15.5;mag have been identified. V and B magnitudes have been determined for 2118 and 2110 stars respectively. Estimations of mass (348 Msun <=M_TOT <=522 Msun), age (t=2.5x 108 yr), distance (r=698 pc) and reddening (EB-V=0.24) of the cluster NGC 7243 have been made.
