Search for high-amplitude Delta Scuti and RR Lyrae stars in Sloan Digital Sky Survey Stripe 82 using principal component analysis
M. Süveges, B. Sesar, M. Váradi +9
We propose a robust principal component analysis (PCA) framework for the exploitation of multi-band photometric measurements in large surveys. Period search results are improved us…
Efficient use of simultaneous multi-band observations for variable star analysis
Maria Süveges, Paul Bartholdi, Andrew Becker +3
The luminosity changes of most types of variable stars are correlated in the different wavelengths, and these correlations may be exploited for several purposes: for variability de…
The variable Universe through the eyes of Gaia
Laurent Eyer, Maria Suveges, Pierre Dubath +5
The ESA Gaia mission will provide a multi-epoch database for a billion of objects, including variable objects that comprise stars, active galactic nuclei and asteroids. We highligh…
Variable Stars: which Nyquist Frequency ?
L. Eyer, P. Bartholdi
In the analysis of variable stars, the problem of sampling is central. This article focusses on the determination of the Nyquist frequency. It is well defined in the case of regula…
Physical parameters of the Algol system TZ Eridani from simultaneous analysis of Geneva 7-colour light curves
F. Barblan, P. Bartholdi, P. North +2
Light curves of the semi-detached eclipsing binary system TZ Eridani in the Geneva 7-colour photometric system were analysed using the Wilson-Devinney programme. The physical and o…
