Lithium Depletion Boundary in a Pre-main-sequence Binary System

Song, Inseok; Bessell, Michael; Zuckerman, B

Description

A lithium depletion boundary is detected in HIP 112312 (GJ 871.1 A and B), an ∼12 Myr old pre-main-sequence binary system. A strong (EW ≈ 300 mÅ) Li λ6708 absorption feature is seen in the secondary (∼M4.5), while no Li λ6708 feature is detected
