摘要：

监视器项目是一个利用欧洲南方天文台和其他天文台的望远镜对年轻疏散星团进行光度和光谱监测的大规模计划。它的主要目标是探测和发现新的低质量食双星，这里讨论了前三个探测到的系统。我们直接从光和径向速度曲线推导出每个系统的组件的质量和半径，并将它们与常用的低质量恒星理论演化模型的预测进行比较。

英文摘要：

The Monitor project is a large-scale program of photometric and spectroscopic monitoring of young open clusters using telescopes at ESO and other observatories. Its primary goal is to detect and characterise new low-mass eclipsing binaries, and the first three detected systems are discussed here. We derive the masses and radii of the components of each system directly from the light and radial velocity curves, and compare them to the predictions of commonly used theoretical evolutionary models of low-mass stars.
