Gaia Data Release 3: Gaia scan-angle dependent signals and spurious periods
B. Holl, C. Fabricius, J. Portell +23
Context: Gaia DR3 time series data may contain spurious signals related to the time-dependent scan angle. Aims: We aim to explain the origin of scan-angle dependent signals and how…
Gaia Data Release 3: Cross-match of Gaia sources with variable objects from the literature
P. Gavras, L. Rimoldini, K. Nienartowicz +22
Context. In the current ever increasing data volumes of astronomical surveys, automated methods are essential. Objects of known classes from the literature are necessary for traini…
Gaia Data Release 3: The Gaia Andromeda Photometric Survey
D. W. Evans, L. Eyer, G. Busso +14
Context. As part of Gaia Data Release 3 (Gaia DR3), epoch photometry has been released for 1.2 million sources centred on M31. This is a taster for Gaia Data Release 4 where all th…
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: Photometric content and validation
D. W. Evans, M. Riello, F. De Angeli +9
Aims. We describe the photometric content of the second data release of the Gaia project (Gaia DR2) and its validation along with the quality of the data. Methods. The validation w…
Short timescale variables in the Gaia era: detection and characterization by structure function analysis
Maroussia Roelens, Laurent Eyer, Nami Mowlavi +7
We investigate the capabilities of the ESA Gaia mission for detecting and character- izing short timescale variability, from tens of seconds to a dozen hours. We assess the efficie…
Gaia Data Release 1: The variability processing & analysis and its application to the south ecliptic pole region
L. Eyer, N. Mowlavi, D. W. Evans +70
The ESA Gaia mission provides a unique time-domain survey for more than one billion sources brighter than G=20.7 mag. Gaia offers the unprecedented opportunity to study variability…
Short timescale variables in stellar clusters: From Gaia to ground-based telescopes
Maroussia Roelens, Sergi Blanco-Cuaresma, Laurent Eyer +6
Combined studies of variable stars and stellar clusters open great horizons, and they allow us to improve our understanding of stellar cluster formation and stellar evolution. In t…
A comparative study of four significance measures for periodicity detection in astronomical surveys
Maria Süveges, Leanne P. Guy, Laurent Eyer +8
We study the problem of periodicity detection in massive data sets of photometric or radial velocity time series, as presented by ESA's Gaia mission. Periodicity detection hinges o…
The variability processing and analysis of the Gaia mission
Laurent Eyer, Dafydd Wyn Evans, Nami Mowlavi +10
We present the variability processing and analysis that is foreseen for the Gaia mission within Coordination Unit 7 (CU7) of the Gaia Data Processing and Analysis Consortium (DPAC)…
