The Gaia GSP-Spec catalogue of interstellar extinctions, and stellar luminosities, radii, and masses

Patrick de Laverny, Alejandra Recio-Blanco, Camila Navarrete +2

The Gaia/DR3 GSP-Spec module has published the atmospheric parameters of up to 5.6 million stars based on the analysis of their Radial Velocity Spectrometer spectra. By combining t…

Surface brightness-colour relations of Milky Way and Magellanic Clouds classical Cepheids based on Gaia magnitudes

M. C. Bailleul, N. Nardetto, V. Hocdé +12

Aims: We derive SBCRs for classical Cepheids in the Milky Way and in the Magellanic Clouds using the photometric data available in the Gaia database, and we quantify the metallicit…

Characterizing the Post-Red Supergiant binary system AFGL 4106 and its complex nebula with SPHERE/VLT

G. Tomassini, E. Lagadec, I. El Mellah +6

Aims: We aim to characterize the physical and morphological properties of the binary system AFGL 4106, composed of two evolved massive stars. Understanding its mass-loss processes…

3D extinction maps of the Milky Way disc from Gaia GSP-Spec parameters

M. Barbillon, A. Recio-Blanco, P. de Laverny +1

3D maps of interstellar dust are crucial for understanding the structure of the Milky Way interstellar medium to apply correction to astrophysical observations affected by dust. We…

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…

The Gaia spectroscopic catalogue of exoplanets and host stars

Patrick de Laverny, Roxanne Ligi, Aurélien Crida +2

Complete, accurate, and precise catalogues of exoplanet host star (EHS) properties are essential to deriving high-quality exoplanet parameters. This paper aims at homogeneously par…
