Chemical evolution of Na, Mg, and Al in the Galactic bulge from UVES data

R. P. Nunes, B. Barbuy, C. Chiappini +9

The formation of the Galactic bulge remains incompletely understood, with evidence pointing to different stellar populations, including a bar-driven component, an inner-disk popula…

Reanalysis of neutron-capture elements in the benchmark r-rich star CS 31082-001

H. Ernandes, M. J. Castro, B. Barbuy +4

We revisit the abundances of neutron-capture elements in the metal-poor ([Fe/H]=-2.9) r-process-rich halo star CS 31082-001. Partly motivated by the development of the new near-ult…

Li-rich giant stars under scrutiny: Binarity, magnetic activity and the evolutionary status after Gaia DR2

B. F. O. Gonçalves, J. S. da Costa, L. de Almeida +2

We present a study of the evolutionary state of a few lithium-rich giant stars based on the Gaia DR2 parallaxes and photometry. We also investigate the chromospheric activity, the…

Modeling of two CoRoT solar analogues constrained by seismic and spectroscopic analysis

M. Castro, F. Baudin, O. Benomar +8

Solar analogues are important stars to study for understanding the properties of the Sun. Evolutionary modeling, combined with seismic and spectroscopic analysis, becomes a powerfu…

Rotation of solar analogs cross-matching Kepler and Gaia DR2

Jose-Dias do Nascimento, Leandro de Almeida, Eduardo Nunes Velloso +10

A major obstacle to interpreting the rotation period distribution for main-sequence stars from Kepler mission data has been the lack of precise evolutionary status for these object…

Optimized cutting off transit algorithm to study stellar rotation from PLATO mission light curves

Leandro de Almeida, Francys Anthony, Ana Carolina Mattiuci +4

Measuring the stellar rotation of one of the components in eclipsing binaries (EBs) or planetary systems is a challenging task. The difficulty is mainly due to the complexity of an…
