3D non-LTE corrections for Li abundance and ^{6}Li/^{7}Li
isotopic ratio in solar-type stars

Tool explanation

This tool utilizes the analytical expressions developed in Harutyunyan G., Steffen M., Mott A. et al. (2018) to compute the 3D non-LTE (NLTE) corrections for lithium abundance (A(Li)) and
^{6}Li/^{7}Li isotopic ratio. The 3D NLTE correction of A(Li), defined as Δ A(Li), is computed as a function of effective temperature (T_{eff}), metallicity ([Fe/H]) and 1D LTE A(Li), whereas the 3D NLTE correction of ^{6}Li/^{7}Li isotopic ratio, defined as Δ ^{6}Li/^{7}Li, is a function of T_{eff}, [Fe/H], surface gravity (log g), projected rotational velocity (v sini), 1D LTE A(Li) and ^{6}Li/^{7}Li ratio.

The analytical expressions used by this tool were derived for a typical range of stellar parameters for solar-type stars, and they are valid for the following ranges of input parameters:
