EROS 2 proper motion survey: a field brown dwarf, and an L dwarf companion to LHS 102
We report the discovery of two L dwarfs (the new spectral class defined for dwarfs cooler than the M type) in a two-epoch CCD proper motion survey of 413 square degrees, complemented by infrared photometry from DENIS. One of them has a strong lithium line, which for very cool dwarfs is a proof of brown dwarf status. The other is a common proper
