论文摘要
这项工作的目的是扩展具有精确建模的基准级蚀的样本，这些样本具有准确确定的质量和半径的二进制文件。 We select four "well-behaved" Kepler binaries, KIC2306740, KIC4076952, KIC5193386 and KIC5288543, each with at least 8 double-lined spectra from the apogee instrument that is part of the Sloan Digital Sky Surveys III and IV, and from the Hobby-Eberly High Resolution Spectrograph.对于所有四个系统，我们获得的质量和半径为2.5％或以下。这些系统中的三个具有超过9天的轨道周期，因此填充了参数空间的下采样区域，用于极具特色的脱落折叠二进制物。我们比较了衍生的质量和半径与梅萨雾等质激素，以确定系统的年龄。发现所有系统都是同时的，表明结果在梅萨雾和菲比之间是一致的。
The purpose of this work is to extend a sample of accurately modeled, benchmark-grade eclipsing binaries with accurately determined masses and radii. We select four "well-behaved" Kepler binaries, KIC2306740, KIC4076952, KIC5193386 and KIC5288543, each with at least 8 double-lined spectra from the apogee instrument that is part of the Sloan Digital Sky Surveys III and IV, and from the Hobby-Eberly High Resolution Spectrograph. We obtain masses and radii with uncertainties of 2.5% or less for all four systems. Three of these systems have orbital periods longer than 9 days, and thus populate an under-sampled region of the parameter space for extremely well-characterized detached eclipsing binaries. We compare the derived masses and radii against MESA MIST isochrones to determine the ages of the systems. All systems were found to be coeval, showing that the results are consistent across MESA MIST and PHOEBE.
