  • The metal–poor end of the Spite plateau 
    Sbordone, L; Bonifacio, P; Caffau, E; Ludwig, H. -G; Behara, N; Gonzalez-Hernandez, J. I; Steffen, M; Cayrel, R; Freytag, B; Van't Veer, C; Molaro, P; Plez, B; Sivarani, T; Spite, M; Spite, F; Beers, T. C; Christlieb, N; François, P; Hill, V (Cambridge University Press, 2010-03)
    We present the largest sample available to date of lithium abundances in extremely metal poor (EMP) Halo dwarfs. Four Teff estimators are used, including IRFM and Hα wings fitting against 3D hydrodynamical synthetic ...
  • The metal–poor end of the Spite plateau: gravity sensitivity of the Hα wings fitting. 
    Sbordone, L; Bonifacio, P; Caffau, E; Ludwig, H. -G; Behara, N; Gonzalez-Hernandez, J. I; Steffen, M; Cayrel, R; Freytag, B; Van't Veer, C; Molaro, P; Plez, B; Sivarani, T; Spite, M; Spite, F; Beers, T. C; Christlieb, N; François, P; Hill, V (Cambridge University Press, 2010-04)
    We recently presented (Sbordone et al., 2009a) the largest sample to date of lithium abundances in extremely metal-poor (EMP) Halo dwarf and Turn-Off (TO) stars. One of the most crucial aspects in estimating Li abundances ...
