Fig. 3


Abundances of lithium vs. Teff (a), logg (b), [Fe/H] (c), V sin i (d), distance (e),and Vm (f), all shown by filled boxes. Cyan squares and blue circles mark fastrotators with high lithium and without notable lithium, respectively. Upper limits for the lithium abundances in the spectra of stars of our sample are marked by arrows. Dwarf stars hosting substellar components (see Jenkins et al. 2017) with and without strong lithium lines in the spectra are marked by large open circles and squares, respectively.The polygon in (a) bounds the approximate extent of the lithium desert and it is drawn here only to guide the eye, as in Ramírez et al. (2012). The NLTE lithium abundance in the Sun (Pavlenko 1989) is shown by the green asterisk in the blue ring. The numeration of stars followsthe ordering os stars in Table A.5.
