摘要

我们根据最新的最大光照时间和文献中的其他时间，以及uvby−β光电光度法，确定了SX Phe星BL Cam的物理参数。根据我们的分析，我们发现这颗恒星是一个双星系统。伴星的质量是根据主星的质量和轨道角来计算的。对于这颗恒星，我们确定其金属丰度[Fe/H]为-1.2±0.3。

A STUDY OF THE SX PHE STAR BL CAM

We determined the physical parameters of the SX Phe star BL Cam from newly available times of maximum light and other times from the literature, as well as from uvby − β photoelectric photometry. From our analysis we found that this star is a binary system. The mass of the companion star was calculated in term of the mass of the primary star and the orbital angle. For this star we determined a metallicity [Fe/H] of −1.2 ± 0.3.
