Close Binary Stars in Planetary Nebulae through Gaia EDR3
(MDPI, 2021)
[Abstract] The aim of this work is to search for evidence of close binary stars associated with planetary nebulae (ionized stellar envelopes in expansion) by mining the astronomical archive of Gaia EDR3. For this task, ...
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 ...
Mining of the Milky Way Star Archive Gaia-DR2: Searching for Binary Stars in Planetary Nebulae
(MDPI AG, 2020-08-31)
[Abstract]
The aim of this work is to search for binary stars associated to planetary nebulae (ionized stellar envelopes in expansion), by mining the astronomical archive of Gaia DR2, that is composed by around 1.7 billion ...
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 ...
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
(EDP Sciences, 2024)
[Abstract] Context. Gravitational waves from black-hole (BH) merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected based on most stellar ...
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 ...
