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…
Extreme-value modelling for the significance assessment of periodogram peaks
M. Süveges
I propose a new procedure to estimate the False Alarm Probability, the measure of significance for peaks of periodograms. The key element of the new procedure is the use of general…
