Infrared-excess sources in VVV: candidate debris discs, SED characterization, and variability analysis
P. Esteves, R. K. Saito, C. Chavero +9
Debris disks around main-sequence stars provide important insights into planetary formation and evolution; however, identifying these systems in the Galactic plane, where high inte…
Lithium abundance and stellar rotation in the Galactic halo and thick disc: Contribution from low-mass giant field stars
Ramiro de la Reza, Felix Llorente de Andrés, Emilio J. Alfaro +1
The stellar evolution of lithium-rich (Li-rich) giant stars at very low metallicities remains largely unexplored to date. Using two recent large LAMOST catalogues of field, low-mas…
The evolution of lithium in FGK dwarf stars. Influence of planets and Galactic migration
F. Llorente de Andrés, R. de la Reza, P. Cruz +4
This work aims to investigate the behaviour of the lithium abundance in stars with and without detected planets. Our study is based on a sample of 1332 FGK main-sequence stars with…
Searching for the nature of stars with debris disks and planets
R. de la Reza, C. Chavero, S. Roca-Fàbrega +3
The nature of the few known solar-mass stars simultaneously containing debris disks and planets remains an open question. A number of works have shown that this property appears to…
The bi-modal Li distribution of the Milky Way's thin-disk dwarf stars: The role of Galactic-scale events and stellar evolution
Santi Roca-Fàbrega, Félix Llorente de Andrés, Carolina Chavero +2
The lithium abundance, A(Li), in stellar atmospheres suffers from various enhancement and depletion processes during the star's lifetime. While several studies have demonstrated th…
The evolution of lithium in FGK dwarf stars: The Li rotation connection and the Li desert
F. Llorente de Andrés, C. Chavero, R. de la Reza +2
We investigate two topics regarding solar mass FGK-type stars, the lithium rotation connection (LRC) and the existence of the "lithium desert". We determine the minimum critical ro…
