The cerium content of the Milky Way as revealed by Gaia DR3 GSP-Spec abundances
G. Contursi, P. de Laverny, A. Recio-Blanco +12
The recent Gaia Third Data Release contains a homogeneous analysis of millions of high-quality Radial Velocity Spectrometer (RVS) stellar spectra by the GSP-Spec module. This led t…
Gaia DR3: Apsis III -- Non-stellar content and source classification
L. Delchambre, C. A. L. Bailer-Jones, I. Bellas-Velidis +78
Context. As part of the third Gaia data release, we present the contributions of the non-stellar and classification modules from the eighth coordination unit (CU8) of the Data Proc…
Stellar ages, masses, extinctions and orbital parameters based on spectroscopic parameters of Gaia DR3
G. Kordopatis, M. Schultheis, P. J. McMillan +13
Gaia DR3 provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than five million targets. When combined with the astrometric…
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: Catalogue Validation
C. Babusiaux, C. Fabricius, S. Khanna +40
The third gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly…
Gaia Data Release 3: Astrophysical parameters inference system (Apsis) I -- methods and content overview
O. L. Creevey, R. Sordo, F. Pailler +86
Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release. They were produced by the Astrophysica…
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…
Gaia Data Release 3: Analysis of RVS spectra using the General Stellar Parametriser from spectroscopy
A. Recio-Blanco, P. de Laverny, P. A. Palicio +77
The chemo-physical parametrisation of stellar spectra is essential for understanding the nature and evolution of stars and of Galactic stellar populations. Gaia DR3 contains the pa…
Identification of new hot subdwarf binary systems by means of Virtual Observatory tools
E. Solano, A. Ulla, E. Pérez-Fernández +7
The estimation of the binary fraction of hot subdwarfs is key to shed light on the different evolution scenarios proposed to explain the loss of the hydrogen envelope during the re…
Solid confirmation of the broad DIB around 864.8 nm using stacked Gaia-RVS spectra
H. Zhao, M. Schultheis, T. Zwitter +26
Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia-RVS spectral window between 846 and 870…
