Detection of lithium in nearby young late-M dwarfs

Phan-Bao, N; Bessell, Michael; Nguyen-Thanh, D; Martin, E L; Ho, P T P; Lee, C F; Parsons, H


Context. Late M-type dwarfs in the solar neighborhood include a mixture of very low-mass stars and brown dwarfs that is difficult to disentangle due to the lack of constraints on their age, such as trigonometric parallax, lithium detection, and space velocity. Aims. We search for young brown dwarf candidates among a sample of 28 nearby late-M dwarfs with spectral types between M5.0 and M9.0, and we also search for debris disks around three of them. Methods. Based on theoretical models, we used...[Show more]
