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: 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 ... -
Gaia Data Release 3: The extragalactic content
(EDP Sciences, 2023-06)[Abstract]: The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes ... -
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, ...
