本文介绍疏散星团NGC 7243的天体测量和光度测量研究结果。利用PDS对97年的天体测量底片进行扫描,获得了2165颗恒星的自行,均方根误差为1:1 masyr ~ 1。总共有211个星系团成员被确定为V= 15:5等。分别测定了2118颗和2110颗恒星的V和B等。对星系团NGC 7243的质量(348 M MTOT 522 M)、年龄(t = 2:5 10 8 yr)、距离(r= 698 pc)和红化(EB V= 0:24)进行了估算。
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 M MTOT 522 M), age (t = 2:5 10 8 yr), distance (r= 698 pc) and reddening (EB V= 0:24) of the cluster NGC 7243 have been made.
