Confirmed detection of lithium in nearby young late-M dwarfs

Brown dwarfs in nearby young associations and moving groups are excellent benchmarks for studying physical properties of these substellar objects at different ages as well as their formation mechanism. In our previous search for nearby young brown dwarfs, we reported the first clear detection of the lithium absorption line in three late-M dwarfs and a marginal detection in one late-M dwarf.
