Drake (2,5) ( Main Astronomical Observatory, Pulkovo, St. Petersburg, Russia, Observatorio Nacional/MCT, Rio de Janeiro, Brazil, Laboratorio Nacional de Computacao Cientifica/MCT, Petropolis | | 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 were obtained by means of PDS scanning of astrometric plates covering the time interval of 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 (348Mo < M < 522Mo), age (t=2.5x10^8 yr), distance (r=698 pc) and reddening (E(B-V)=0.24) of the cluster NGC 7243 have been made. | | Source: | arXiv, astro-ph/0212496 | | Services: | Forum | Review | PDF | Favorites | |
