Abstract

We analyze multicolor light curves of six totally eclipsing, short-period W UMa binaries and derive, for the first time, their orbital and stellar parameters. The mass ratios are established robustly through an automated q-search procedure that performs an heuristic survey of the parameter space. Five stars belong to the W and one to the A subtype. The mass ratios range from 0.23 to 0.51 and the fillouts from $10\%$ to $15\%$. We estimate the ages and discuss the evolutionary status of these objects in comparison with a sample of other short-period W UMa binaries from the literature.

六个完全黯淡的W UMa二进制文件的光曲线分析

摘要

我们分析了六个完全遮盖，短周期的W UMa双星的多色光曲线，并首次导出了它们的轨道和恒星参数。通过执行参数空间的启发式调查的自动q搜索程序，可以可靠地建立质量比。五颗星属于W，一颗属于A亚型。质量比范围为0.23至0.51，填充范围为$ 10 \％$至$ 15 \％$。我们估计了年龄，并与文献中其他短期WUMa双星的样本进行了比较，讨论了这些物体的进化状态。
