论文摘要
VRI光曲线是针对低质量黯然失色的二进制V608 CAM的测量，作为我们长期观察项目的一部分，用于研究以短轨道时期的远离二进制文件。根据Gaia的结果，Phoebe中的Tess Light Curve解决方案结果为分离的配置，其中主组件的温度固定为$ T_1 = 5300 $ K，该结果给出了$ T_2 = 4110 \ PM 50 $ 50 $ K。主要成分的光谱类型得出为K0，估计光度质量比$ q = 0.92 \ pm 0.07 $。估计了次级成分表面上冷区域的特征和时间变化，并归因于该黯然失色的二进制的明显周期变化，其周期约为2.4年。
The VRI light curves were measured for the low-mass eclipsing binary V608 Cam as a part of our long-term observational project for studying of eclipsing binaries with a short orbital period. The Tess light curve solution in Phoebe results to the detached configuration, where the temperature of primary component was fixed to $T_1 = 5300$ K according to Gaia results, which gives us $T_2 = 4110 \pm 50$ K for the secondary. The spectral type of the primary component was derived to be K0 and the photometric mass ratio was estimated $q = 0.92 \pm 0.07$. Characteristics and temporal variation of the cold region on the surface of the secondary component were estimated and are attributed to apparent period changes of this eclipsing binary with a cycle of about 2.4 yr.
