TOI-1759 b: a transiting sub-Neptune around a low mass star characterized with SPIRou and TESS
Eder Martioli, Guillaume Hébrard, Pascal Fouqué +57
We report the detection and characterization of the transiting sub-Neptune TOI-1759 b, using photometric time-series from TESS and near infrared spectropolarimetric data from SPIRo…
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…
Galaxy Mergers: A Search for Chemical Signatures
Inese I. Ivans, Bruce Carney, Luisa de Almeida +1
We have gathered high resolution echelle spectra for more than two dozen high-velocity metal-poor field stars, including BD+80 245, a star previously known to have extremely low [a…
A Search for Chemical Signatures of Galactic Mergers
Inese I. Ivans, Bruce Carney, Luisa de Almeida +1
We present preliminary abundance analyses of a group of high-velocity metal-poor stars. This report describes our work in progress. We examine the derived abundances in the context…
