The light-curve modulation of XY And and UZ Vir - Two Blazhko RR Lyrae stars with additional frequencies
Á. Sódor, G. Hajdu, J. Jurcsik +5
A thorough analysis of multicolour CCD observations of two modulated RRab-type variables, XY And and UZ Vir is presented. These Blazhko stars show relatively simple light-curve mod…
First Results of The Konkoly Blazhko Survey II
Á. Sódor, J. Jurcsik, L. Molnár +17
The two parts of the Konkoly Blazhko Survey (KBS I and II) are introduced. The most important preliminary findings of the second part are presented in comparison to the results of…
Long-term photometric monitoring of Messier 5 variables: II. Blazhko stars
J. Jurcsik, B. Szeidl, C. Clement +2
The light curves of 50 RRab (RR0) stars in M5 collected in Paper I are investigated to detect Blazhko modulation. 18 Blazhko stars are identified, and modulation is suspected in tw…
Long-term photometric monitoring of Messier 5 variables: I. Period changes of RR Lyrae stars
B. Szeid, Zs. Hurta, J. Jurcsik +2
The period changes of 86 M5 RR Lyrae stars have been investigated on a one-hundred-year time base. The published observations have been supplemented by archival Asiago, Konkoly and…
The Multi-periodic Blazhko Modulation of CZ Lacertae
Á. Sódor, J. Jurcsik, B. Szeidl +7
Thorough analysis of the multicolour CCD observations of the RRab-type variable, CZ Lacertae is presented. The observations were carried out in two consecutive observing seasons in…
Four-colour photometry of EY Dra: a study of an ultra-fast rotating active dM1-2e star
K. Vida, K. Oláh, Zs. Kővári +8
We present more than 1000-day long photometry of EY Draconis in BV(RI)C passbands. The changes in the light curve are caused by the spottedness of the rotating surface. Modelling o…
