Lithium-rich M-dwarfs at the ZAMS: Evidence for planetary engulfment?
R. D. Jeffries, R. J. Jackson, I. Baraffe
We identify 6 early M-dwarfs, in 3 open clusters (NGC 2451a, Blanco 1 and NGC 2516) at ages of 50-200 Myr, that are anomalously enriched in lithium compared with Li-depleted siblin…

The growth of a lithium abundance dispersion in pre main sequence stars
R. J. Jackson, R. D. Jeffries, E. Tognelli
Lithium is predicted, and observed, to be depleted in contracting, low-mass pre main sequence (PMS) stars. Yet these stars reach the zero age main sequence (ZAMS) with a spread in…
