Low-Mass and Sub-stellar Eclipsing Binaries in Stellar Clusters

摘要: We highlight the importance of eclipsing double-line binaries in our understanding on star formation and evolution. review recent discoveries low-mass sub-stellar belonging to star-forming regions, open clusters, globular clusters identified by ground-based surveys space missions with high-resolution spectroscopic follow-up. These provide benchmark systems known distances, metallicities, ages calibrate masses radii predicted state-of-the-art evolutionary models a few percent. report their density discuss current limitations accuracy physical parameters. future opportunities guidelines fill gaps age metallicity improve further knowledge stars brown dwarfs.
