在低质量恒星中,食双星的经验质量-半径关系与恒星模型之间的差异是一个亟待解决的问题,因为它涉及到我们对恒星物理的基本理解。观测有低质量伴星的明亮食双星样本,是tres调查的副产品,为显著改进观测数据库提供了机会。因此,我们建议继续聚焦高分辨率光谱,以获得径向速度曲线,以便确定几个新的低质量恒星的可靠质量和半径。特别强调那些具有可检测的次要光谱特征的系统。
英文摘要
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.
