Non-LTE effects on the lead and thorium abundance determinations for cool stars
Context. Knowing accurate lead abundances of metal-poor stars provides constraints on the Pb production mechanisms in the early Galaxy. Accurately deriving thorium abundances permits a nucleo-chronometric age determination of the star. Aims. We aim to improve the calculation of the Pb i and Th ii li...
