The AMBRE Project: Line-broadening and stellar rotation of ESO/FEROS archived spectra
F. Bado, P. de Laverny, Z. Kam +3
Stellar rotation is a fundamental parameter in stellar studies. However, large homogeneous catalogues of rotational velocities derived from high-resolution stellar spectra are stil…
A comprehensive Gaia view of ellipsoidal and rotational red giant binaries
Camila Navarrete, Alejandra Recio-Blanco, Patrick de Laverny +1
The latest Gaia Focused Product Release (FPR) provided variability information for 1000 long-period red giant binaries, the largest sample to date of this binary type having…
Gaia/GSP-spec spectroscopic properties of gamma Doradus pulsators
P. de Laverny, A. Recio-Blanco, C. Aerts +1
Gaia/DR3 has provided a large sample of new g-mode pulsators, among which~11,600 are Gam Dor stars. This work present the spectroscopic parameters of these Gam Dor pulsators estima…
The AMBRE Project: Lead abundance in Galactic stars
G. Contursi, P. de Laverny, A. Recio-Blanco +4
The chemical evolution of neutron capture elements in the Milky Way is still a matter of debate. Although more and more studies investigate their chemical behaviour, there is still…
The Gaia-ESO Survey DR5.1 and Gaia DR3 GSP-Spec: a comparative analysis
M. Van der Swaelmen, C. Viscasillas Vazquez, L. Magrini +10
(abridged) The third data release of Gaia, has provided stellar parameters, metallicity [M/H], [α/Fe], individual abundances, broadening parameter from its RVS spectra for about 5.…
Production of s-process elements in AGB stars as revealed by Gaia GSP-spec abundances
G. Contursi, P. de Laverny, A. Recio-Blanco +2
The recent parameterisation by the GSP-spec module of Gaia/RVS spectra has produced an homogeneous catalogue of about 174,000 AGB stars. Among the 13 chemical elements presented in…
