Departures from LTE for neutral Li in late-type stars

Lind, K; Asplund, Martin; Barklem, Paul S


We perform non-LTE calculations of lithium in late-type stars for a wide range of stellar parameters, including quantum mechanical cross-sections for collisions with neutral hydrogen and the negative hydrogen ion. Non-LTE abundance corrections for the lithium resonance line at 670.7 nm and the subordinate line at 610.3 nm, are calculated using 1D MARCS model atmospheres spanning a grid Teff = [4000, 8000] K, log g = [1.0,5.0], and [Fe/H] = [0.0, -3.0], for lithium abundances in the range A (Li)...[Show more]
