Gaia Data Release 2: Observations of solar system objects
(EDP Sciences, 2018)
[Abstract] Context. The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Data Release 2 (DR2) contains the observations ...
Gaia Data Release 2: Summary of the contents and survey properties
(EDP Sciences, 2018-08)
[Abstract]: Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighter than magnitude ...
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 1: Summary of the astrometric, photometric, and survey properties
(EDP Sciences, 2016-11)
[Abstract]: Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A ...
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). ...
On the estimation of stellar parameters with uncertainty prediction from Generative Artificial Neural Networks: application to Gaia RVS simulated spectra
(EDP Sciences, 2016-10)
[Abstract]: Aims. We present an innovative artificial neural network (ANN) architecture, called Generative ANN (GANN), that computes the forward model, that is it learns the function that relates the unknown outputs (stellar ...
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 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: Acceleration of the Solar System from Gaia Astrometry
(EDP Sciences, 2021)
[Abstract] Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric ...
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 ...
