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. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Pulsating star research and the Gaia revolution
Laurent Eyer, Gisella Clementini, Leanne P. Guy +17
In this article we present an overview of the ESA Gaia mission and of the unprecedented impact that Gaia will have on the field of variable star research. We summarise the contents…
Gaia eclipsing binary and multiple systems. Two-Gaussian models applied to OGLE-III eclipsing binary light curves in the Large Magellanic Cloud
N. Mowlavi, I. Lecoeur-Taïbi, B. Holl +11
The advent of large scale multi-epoch surveys raises the need for automated light curve (LC) processing. This is particularly true for eclipsing binaries (EBs), which form one of t…
Gaia Eclipsing Binary and Multiple Systems. A study of detectability and classification of eclipsing binaries with Gaia
A. Kochoska, N. Mowlavi, A. Prsa +5
In the new era of large-scale astronomical surveys, automated methods of analysis and classification of bulk data are a fundamental tool for fast and efficient production of delive…
Gaia eclipsing binary and multiple systems. Supervised classification and self-organizing maps
M. Süveges, F. Barblan, I. Lecoeur-Taïbi +6
Large surveys producing tera- and petabyte-scale databases require machine-learning and knowledge discovery methods to deal with the overwhelming quantity of data and the difficult…
