Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program: Galactic stellar populations and planets⋆⋆⋆⋆⋆⋆

Year: 2012

Type: article

Abstract: Context. We performed a uniform and detailed abundance analysis of 12 refractory elements (Na, Mg, Al, Si, Ca, Ti, Cr, Ni, Co, Sc, Mn, and V) for a sample of 1111 FGK dwarf stars from the HARPS GTO planet search program. Of these stars, 109 are known to harbor giant planetary companions and 26 stars are exclusively hosting Neptunians and super-Earths.
