论文摘要
恒星的质量和半径可以通过将黯淡的二进制光曲线与光谱轨道结合在一起来得出。在我们以前的工作中，我们对使用Phoebe的超新星（ASAS-SN）光曲线进行了全天自动化的调查。在这里，我们将结果与Gaia数据版本3的128个双线光谱轨道结合在一起。我们在视觉上检查了较低主序列和巨型分支的双线光谱二进制曲线的ASAS-SN光曲线，并在我们的样品中添加了11个二元。我们发现，只有50％的系统具有与ASAS-SN值一致的GAIA周期和偏心率。我们使用司仪和菲比（Phoebe）确定质量和半径，总计122颗恒星，中位数不确定性分别为7.9％和6.3％。
Masses and radii of stars can be derived by combining eclipsing binary light curves with spectroscopic orbits. In our previous work, we modeled the All-Sky Automated Survey for Supernovae (ASAS-SN) light curves of more than 30,000 detached eclipsing binaries using PHOEBE. Here we combine our results with 128 double-lined spectroscopic orbits from Gaia Data Release 3. We visually inspect ASAS-SN light curves of double-lined spectroscopic binaries on the lower main sequence and the giant branch, adding 11 binaries to our sample. We find that only 50% of systems have Gaia periods and eccentricities consistent with the ASAS-SN values. We use emcee and PHOEBE to determine masses and radii for a total of 122 stars with median fractional uncertainties of 7.9% and 6.3%, respectively.
