Gaia method paper: an algorithm to detect flare events in Gaia time-series
E. Distefano, A. C. Lanzafame, A. F. Lanza +14
The third Gaia data release (GDR3) includes the gdr3_rotmod catalogue of 474026 stars with variability that is attributed to magnetic activity analogous to that observed in the Sun…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
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 ni…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
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-velocit…
Gaia Data Release 3. Summary of the variability processing and analysis
L. Eyer, M. Audard, B. Holl +55
Context. Gaia has been in operations since 2014. The third Gaia data release expands from the early data release (EDR3) in 2020 by providing 34 months of multi-epoch observations t…
Gaia DR3: Specific processing and validation of all-sky RR Lyrae and Cepheid stars -- The RR Lyrae sample
G. Clementini, V. Ripepi, A. Garofalo +18
Gaia DR3 publishes a catalogue of full-sky RR Lyrae stars (RRLs) observed during the initial 34 months of science operations, that were processed through the Specific Object Study…
Gaia DR3: Specific processing and validation of all-sky RR Lyrae and Cepheid stars -- The Cepheid sample
V. Ripepi, G. Clementini, R. Molinaro +19
Context. Cepheids are pulsating stars that play a crucial role in several astrophysical contexts. Among the different types, the Classical Cepheids are fundamental tools for the ca…
Gaia Data Release 3: The second Gaia catalogue of Long-Period Variable candidates
T. Lebzelter, N. Mowlavi, I. Lecoeur-Taibi +9
The third Gaia Data Release, covering 34 months of data, includes the second Gaia catalogue of long-period variables (LPVs), with G variability amplitudes larger than 0.1 mag (5-95…
Gaia Data Release 3. Rotational modulation and patterns of colour variations in solar-like variables
E. Distefano, A. C. Lanzafame, E. Brugaletta +15
The Gaia third Data Release (DR3) presents a catalogue of 474\,026 stars with variability induced by magnetic activity. For each star, the catalogue provides a list of about 70 par…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Large-amplitude variables in Gaia Data Release 2. Multi-band variability characterization
N. Mowlavi, L. Rimoldini, D. W. Evans +11
The second data release (DR2) of Gaia provides mean photometry in three bands for 1.4 billion sources, but light curves and variability properties are available for only $\si…
Gaia's revolution in stellar variability
L. Eyer, L. Rimoldini, L. Rohrbasser +15
Stellar variability studies are now reaching a completely new level thanks to ESA's Gaia mission, which enables us to locate many variable stars in the Hertzsprung-Russell diagram…
Gaia Data Release 2: Rotational modulation in late-type dwarfs
A. C. Lanzafame, E. Distefano, S. Messina +11
We present the methods devised to identify the BY Dra variables candidates in Gaia DR2 and infer their variability parameters. BY Dra candidates are pre-selected from their positio…
All-sky RR Lyrae Stars in the Gaia Data
Lorenzo Rimoldini, Laurent Eyer, Nami Mowlavi +22
The second Gaia data release is expected to contain data products from about 22 months of observation. Based on these data, we aim to provide an advance publication of a full-sky G…
Gaia Data Release 2: Summary of the variability processing & analysis results
B. Holl, M. Audard, K. Nienartowicz +60
The Gaia Data Release 2 (DR2): we summarise the processing and results of the identification of variable source candidates of RR Lyrae stars, Cepheids, long period variables (LPVs)…

Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Pulsating star research and the Gaia revolution
Laurent Eyer, Gisella Clementini, Leanne P. Guy +17
In this article we present an overview of the ESA Gaia mission and of the unprecedented impact that Gaia will have on the field of variable star research. We summarise the contents…
