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…
Solar twins in Gaia DR3 GSP-Spec I. Building a large catalog of Solar twins with ages
Daisuke Taniguchi, Patrick de Laverny, Alejandra Recio-Blanco +2
[Abbreviated] Context. Solar twins, stars whose stellar parameters (Teff, log g, and [M/H]) are very close to the Solar ones, offer a unique opportunity to investigate Galactic arc…
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…
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 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…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
Ultracool dwarfs in Gaia DR3
L. M. Sarro, A. Berihuete, R. L. Smart +36
Aims. In this work we use the Gaia DR3 set of ultracool dwarf candidates and complement the Gaia spectrophotometry with additional photometry in order to characterise its global pr…
Gaia Data Release 3: Analysis of the Gaia BP/RP spectra using the General Stellar Parameterizer from Photometry
R. Andrae, M. Fouesneau, R. Sordo +80
We present the General Stellar Parameterizer from Photometry (GSP-Phot), which is part of the astrophysical parameters inference system (Apsis). GSP-Phot is designed to produce a h…
Gaia Data Release 3: Apsis II -- Stellar Parameters
M. Fouesneau, Y. Frémat, R. Andrae +78
The third Gaia data release contains, beyond the astrometry and photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra (BP and RP) and the spec…
Gaia Data Release 3. Stellar chromospheric activity and mass accretion from Ca II IRT observed by the Radial Velocity Spectrometer
A. C. Lanzafame, E. Brugaletta, Y. Frémat +82
The Gaia Radial Velocity Spectrometer provides the unique opportunity of a spectroscopic analysis of millions of stars at medium-resolution in the near-infrared. This wavelength ra…
GSP-spec line list for the parametrisation of Gaia -RVS stellar spectra
G. Contursi, P. de Laverny, A. Recio-Blanco +1
The Gaia mission is a magnitude-limited whole-sky survey that collects an impressive quantity of astrometric, spectro-photometric and spectroscopic data. Among all the on-board ins…
Geometry of the Draco C1 Symbiotic Binary
Hannah M. Lewis, Borja Anguiano, Keivan G. Stassun +14
Draco C1 is a known symbiotic binary star system composed of a carbon red giant and a hot, compact companion -- likely a white dwarf -- belonging to the Draco dwarf spheroidal gala…
