Gaia Data Release 3: Analysis of the Gaia BP/RP spectra using the General Stellar Parameterizer from Photometry
(EDP Sciences, 2023-06)[Abstract]: Context. The astrophysical characterisation of sources is among the major new data products in the third Gaia Data Release (DR3). In particular, there are stellar parameters for 471 million sources estimated ... -
Gaia Data Release 3: Apsis. II. Stellar parameters
(EDP Sciences, 2023-06)[Abstract]: Context. The third Gaia data release (Gaia DR3) contains, beyond the astrometry and photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra (BP and RP) and the spectrograph ... -
Gaia Data Release 3: Apsis. III. Non-stellar content and source classification
(EDP Sciences, 2023-06)[Abstract]: 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 Processing and Analysis Consortium, ... -
Gaia Data Release 3: Astrophysical parameters inference system (Apsis). I. Methods and content overview
(EDP Sciences, 2023-06)[Abstract]: Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release, and were produced by the Astrophysical parameters inference system ... -
Gaia Data Release 3: Catalogue validation
(EDP Sciences, 2023-06)[Abstract]: Context. 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 two billion sources. ... -
Gaia Data Release 3: Mapping the asymmetric disc of the Milky Way
(EDP Sciences, 2023)[Abstract] Context. With the most recent Gaia data release, the number of sources with complete 6D phase space information (position and velocity) has increased to well over 33 million stars, while stellar astrophysical ... -
Gaia Data Release 3: Stellar chromospheric activity and mass accretion from Ca II IRT observed by the Radial Velocity Spectrometer
(EDP Sciences, 2023-06)[Abstract]: Context. The Gaia Radial Velocity Spectrometer (RVS) provides the unique opportunity of a spectroscopic analysis of millions of stars at medium resolution (λ/I λ'a '11'500) in the near-infrared (845'872 nm). ... -
Gaia Data Release 3: Stellar multiplicity, a teaser for the hidden treasure
(EDP Sciences, 2023)[Abstract] Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing binaries, and combinations of ... -
Gaia Data Release 3: Summary of the content and survey properties
(EDP Sciences, 2023)[Abstract] Context. We present the third data release of the European Space Agency’s Gaia mission, Gaia DR3. This release includes a large variety of new data products, notably a much expanded radial velocity survey and a ... -
Gaia Data Release 3: The Galaxy in your preferred colours: Synthetic photometry from Gaia low-resolution spectra
(EDP Sciences, 2023-06)[Abstract]: Gaia Data Release 3 provides novel flux-calibrated low-resolution spectrophotometry for '220 million sources in the wavelength range 330 nm ≤ λ ≤ 1050 nm (XP spectra). Synthetic photometry directly tied to a ... -
Gaia Early Data Release 3: Structure and Properties of the Magellanic Clouds
(EDP Sciences, 2021)[Abstract] Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements ... -
Gaia Early Data Release 3: Summary of the Contents and Survey Properties
(EDP Sciences, 2021)[Abstract] Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the list of ... -
Gaia Early Data Release 3: The celestial reference frame (Gaia-CRF3)
(EDP Sciences, 2022-11-23)[Abstract]: Context. Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains ... -
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
(EDP Sciences, 2021)[Abstract] Aims. We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue through comparisons to the full data release, ... -
Gaia Focused Product Release: Radial velocity time series of long-period variables
(EDP Sciences, 2023)[Abstract] Context. 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-velocity data planned with ... -
Gaia Focused Product Release: Sources from Service Interface Function image analysis: Half a million new sources in omega Centauri
(EDP Sciences, 2023)[Abstract] Context. 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 nine selected regions ...
