In low-mass stars, the discrepancy between the empirical mass-radius relation from eclipsingbinaries and stellar models is an urgent problem, as it touches on our basic understandingof stellar physics. Observing a sample of bright eclipsing binaries with low-mass companions,obtained as by-product of the TrES-survey, offers the chance to improve the observationaldatabase significantly. We therefore propose to continue FOCES high resolutionspectroscopy to obtain radial velocity curves in order to determine reliable masses and radiifor several new low-mass stars. Special emphasis is placed on those systems with detectablespectroscopic features of the secondary.

在低质量的恒星中，经验质量 - 拉迪乌斯之间的差异与日食模型与恒星模型之间的差异是一个紧迫的问题，因为它涉及我们恒星物理学的基本理解。观察以低质量伴侣为副产品的亮质伴侣的亮叶二进制文件的样本，提供了显着改善观察数据库酶的机会。因此，我们建议继续进行高分辨率光谱镜，以获得径向速度曲线，以确定可靠的质量和辐射器几个新的低质量恒星。特别重点放在那些具有次要特征的系统的系统上。
