An extensive photometric study of the Blazhko RR Lyrae star DM Cyg
J. Jurcsik, Zs. Hurta, A. Sodor +10
DM Cyg, a fundamental mode RRab star was observed in the 2007 and 2008 seasons in the frame of the Konkoly Blazhko Survey. Very small amplitude light curve modulation was detected…
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…
Detecting short period variable stars with Gaia
M. Varadi, L. Eyer, S. Jordan +2
We analyzed the frequency domain of time series of simulated ZZ Ceti light-curves to investigate the detectability and period recovery performance of short period variables (period…
A photometric monitoring of bright high-amplitude delta Scuti stars. II. Period updates for seven stars
A. Derekas, L. L. Kiss, P. Szekely +10
We present new photometric data for seven high-amplitude delta Scuti stars. The observations were acquired between 1996 and 2002, mostly in the Johnson photometric system. For one…
Pulsational and evolutionary analysis of the double-mode RR Lyrae star BS Com
I. Dekany, G. Kovacs, J. Jurcsik +8
We derive the basic physical parameters of the field double-mode RR Lyrae star BS Com from its observed periods and the requirement of consistency between the pulsational and evolu…
The first CCD photometric study of the open cluster NGC 2126
A. Gaspar, L. L. Kiss, T. R. Bedding +6
We present the first CCD photometric observations of the northern open cluster NGC 2126. Data were taken on eight nights in February and December 2002 with a total time span of ~57…
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…
Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects
Gaia Collaboration, F. van Leeuwen, A. Vallenari +589
Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry,…
