  • New determination of abundances and stellar parameters for a set of weak G-band stars 
    Palacios, A; Jasniewicz, G; Masseron, T; Thevenin, F; Itam-Pasquet, J; Parthasarathy, M (EDP Sciences, 2016-03)
    Context. Weak G -band (wGb) stars are a very peculiar class of red giants; th ey are almost devoided of carbon and often present mild lithium enrichment. Desp ite their very puzzling abundance pa tterns, very few ...
  • Weak G-band stars on the H-R diagram: clues to the origin of the Li anomaly 
    Palacios, A; Parthasarathy, M; Bharat Kumar, Y; Jasniewicz, G (EDP Sciences, 2012-02)
    Aims. Weak G-band (WGB) stars are a rare class of cool luminous stars that present a strong depletion in carbon, but also lithium abundance anomalies that have been little explored in the literature since the first discovery ...
