  • Optical spectroscopy is used to confirm membership for 8 low- mass candidates in the young Beta Pic moving group (BPMG) via their radial velocities, chromospheric activity and kinematic parallaxes. We searched for the presence of the Li I 6708 ˚ A resonance feature and combined the results with literature measurements of other BPMG members to find the agedependent lithium depletion boundary (LDB) ‐ the luminosity at which Li remains unburned in a coeval group. The LDB age of the BPMG is 21 ± 4… CONTINUE READING
