论文摘要
我们强调了对恒星形成和进化的理解,使双线二进制文件黯然失色。我们回顾了属于恒星形成区域,开放式群集以及通过基于地面的调查和高分辨率光谱随访的空间任务确定的低质量和亚赛车黯然失色的二进制物的发现。这些发现提供了具有已知距离,金属性和年龄的基准系统,以校准由最新的进化模型预测的质量和半径,达到百分之几。我们报告它们的密度,并讨论当前对物理参数准确性的局限性。我们讨论未来的机会,并强调未来的指南,以填补年龄和金属性空白,以进一步提高我们对低质量恒星和棕色矮人的了解。
We highlight the importance of eclipsing double-line binaries in our understanding on star formation and evolution. We review the recent discoveries of low-mass and sub-stellar eclipsing binaries belonging to star-forming regions, open clusters, and globular clusters identified by ground-based surveys and space missions with high-resolution spectroscopic follow-up. These discoveries provide benchmark systems with known distances, metallicities, and ages to calibrate masses and radii predicted by state-of-the-art evolutionary models to a few percent. We report their density and discuss current limitations on the accuracy of the physical parameters. We discuss future opportunities and highlight future guidelines to fill gaps in age and metallicity to improve further our knowledge of low-mass stars and brown dwarfs.
