Gaia Data Release 2: All-sky classification of high-amplitude pulsating stars

L. Rimoldini, B. Holl, M. Audard +23

More than half a million of the 1.69 billion sources in Gaia Data Release 2 (DR2) are published with photometric time series that exhibit light variations during the 22 months of o…

Gaia Data Release 2. Summary of the contents and survey properties

Gaia Collaboration, A. G. A. Brown, A. Vallenari +4

We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…

Gaia Data Release 2: The first Gaia catalogue of long-period variable candidates

N. Mowlavi, I. Lecoeur-Taïbi, T. Lebzelter +13

Gaia DR2 provides a unique all-sky catalogue of 550'737 variable stars, of which 151'761 are long-period variable (LPV) candidates with G variability amplitudes larger than 0.2 mag…

Gaia Data Release 2. Short-timescale variability processing and analysis

M. Roelens, L. Eyer, N. Mowlavi +13

The Gaia DR2 sample of short-timescale variable candidates results from the investigation of the first 22 months of Gaia photometry for a subsample of sources at the Gaia faint end…

Gaia Data Release 2: Properties and validation of the radial velocities

D. Katz, P. Sartoretti, M. Cropper +51

For Gaia DR2 (GDR2), 280 million spectra, collected by the RVS instrument on-board Gaia, were processed and median radial velocities were derived for 9.8 million sources brighter t…

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)…
