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)…
Automated eclipsing binary detection: applying the Gaia CU7 pipeline to Hipparcos
Berry Holl, Nami Mowlavi, Isabelle Lecoeur-Taïbi +8
We demonstrate the eclipsing binary detection performance of the Gaia variability analysis and processing pipeline using Hipparcos data. The automated pipeline classifies 1,067 (0.…
