Gaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
(EDP Sciences, 2023)
[Abstract] Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars and extragalactic objects that are probably caused by large and complex molecules in the galactic interstellar ...
Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
(EDP Sciences, 2023)
[Abstract] Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over ...
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 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 ...
The Gaia mission
(EDP Sciences, 2016-11)
[Abstract]: Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was ...
Gaia Data Release 3: Chemical cartography of the Milky Way
(EDP Sciences, 2023-06)
[Abstract]: Context. The motion of stars has been used to reveal details of the complex history of the Milky Way, in constant interaction with its environment. Nevertheless, to reconstruct the Galactic history puzzle in ...
Gaia Data Release 3: Analysis of RVS spectra using the General Stellar Parametriser from spectroscopy
(EDP Sciences, 2023-06)
[Abstract]: Context. The chemo-physical parametrisation of stellar spectra is essential for understanding the nature and evolution of stars and of Galactic stellar populations. A worldwide observational effort from the ...
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: 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: Exploring and mapping the diffuse interstellar band at 862 nm
(EDP Sciences, 2023-01)
[Abstract]: Context. Diffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. DIBs play an important role in the life cycle of the ...
