Files

Lithium Depletion Boundary (LDB) available for the following chemical compositions:

• [Fe/H] = +0.1, Y=0.281, Z = 0.016
• [Fe/H] = +0.0, Y=0.274, Z = 0.013
• [Fe/H] = -0.1, Y=0.269, Z = 0.010
• [Fe/H] = -0.5, Y=0.257, Z = 0.004
• [Fe/H] = -1.0, Y=0.252, Z = 0.002

Each file contains the stellar mass (M_sun), age (Myr), log L/L_sun, log T_eff (K), log R/R_sun, and log g (cm s^-2) at the LDB.

LDB is defined as the model in which lithium is depleted by a factor of 100.

Pre-Main Sequence Models

The pre-main sequence models have been computed adopting:

• mixing-length parameter α = 1.00
• initial deuterium abundance X_D = 2 · 10^-5
• heavy element mixture by Asplund et al. (2009)
• stellar mass in the range M = 0.06 - 0.4 M_sun
