Origin of the heavy elements in HD 140283. Measurement of europium abundance
C. Siqueira Mello, B. Barbuy, M. Spite +1
HD 140283 is a nearby (V=7.7) subgiant metal-poor star, extensively analysed in the literature. Although many spectra have been obtained for this star, none showed a signal-to-nois…
Colour-Magnitude Diagrams of candidate age-gap filling LMC clusters
Eduardo Balbinot, Basilio Santiago, Leandro Kerber +2
The LMC has a rich star cluster system spanning a wide range of ages and masses. One striking feature of the LMC cluster system is the existence of an age gap between 3-10 Gyrs. Fo…
Ages, metallicities and -element enhancement for galaxies in Hickson compact groups
C. Mendes de Oliveira, P. Coelho, J. J. González +1
Central velocity dispersions and eight line-strength Lick indices have been determined from 1.3 resolution long-slit spectra of 16 elliptical galaxies in Hickson compact g…
