Emerging trends in metallicity and lithium properties of debris disc stars
C. Chavero, R. de la Reza, L. Ghezzi +5
Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently stu…

The s-process enriched star HD 55496: origin from a globular cluster or from the tidal disruption of a dwarf galaxy?
C. B. Pereira, N. A. Drake, F. Roig
We present a new abundance analysis of HD 55496, previously known as a metal-poor barium star. We found that HD 55496 has a metallicity [Fe/H] and is s-process enriched. W…

High-resolution spectroscopic observations of the new CEMP-s star CD-50776
M. Roriz, C. B. Pereira, N. A. Drake +2
Carbon enhanced metal poor (CEMP) stars are a particular class of low metalicity halo stars whose chemical analysis may provide important constrains to the chemistry evolution of t…
