Analysis of the Non-LTE Lithium Abundance for a Large Sample of F-, G-, and K-Giants and Supergiants

Abstract: A five-dimensional interpolation method and corresponding computer program are developed for using published calculations to determine the non-LTE correction NLTE  to the lithium abundance (Li) log derived from the Li I 6707.8 Å line. The NLTE ∆ values is determined from the following five parameters: NLTE the effective temperature T eff , the acceleration of gravity logg, the metallicity index [Fe/H], the microturbulent velocity V t , and the LTE Li abundance logε(Li) . The program is used to calculate valu… Show more

“…The first reported the lithium abundance for 55 FGK-supergiants and giants, while the second raised the sample size to 146. Figure 7 shows the lithium abundances logLi from these two papers as functions of mass M. The open symbols show the data [35] and the solid symbols, the data from [36]. The triangles represent an upper bound for logε Li (that is, the lithium line is not observed in the spectra of these stars).…”

“…In Table 7, we present our estimations of both the LTE and non‐LTE lithium abundances log ϵ (Li) for program giants. The non‐LTE corrections Δ NLTE are found with the LiCOR code (Lyubimkov & Petrov 2017) that is based on Lind et al's (2009) non‐LTE calculations. One may see that the corrections are within 0.2–0.4 dex and they are greater (0.35–0.38 dex) for the three coolest giants with T eff ≈ 4,000 K.…”
