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…
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…
Revealing δ Cephei's Secret Companion and Intriguing Past
Richard I. Anderson, Johannes Sahlmann, Berry Holl +5
Classical Cepheid variable stars are crucial calibrators of the cosmic distance scale thanks to a relation between their pulsation periods and luminosities. Their archetype, δ Ceph…
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.…
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…
