论文摘要
我们分析了六个完全黯然失色的，短周期的二进制文件的多色光曲线，并首次衍生出它们的轨道和恒星参数。通过对参数空间进行启发式调查的自动Q搜索程序来牢固地建立质量比。五星星属于W，一个属于A子类型。质量比范围为0.23至0.51范围，夹心范围为10％至15％。我们估计年龄并讨论这些物体的进化状态，并与文献中其他短期二进制文件的样本相比。
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 a 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.
