Doppler maps and surface differential rotation of EI Eri from the MUSICOS 1998 observations
Zs. Kővári, A. Washuettl, B. H. Foing +4
We present time-series Doppler images of the rapidly-rotating active binary star EI Eri from spectroscopic observations collected during the MUSICOS multi-site campaign in 1998, si…
An extensive photometric study of the Blazhko RR Lyrae star MW Lyr: II. Changes in the physical parameters
J. Jurcsik, Á. Sódor, B. Szeidl +11
The analysis of the multicolour photometric observations of MW Lyr, a large modulation amplitude Blazhko variable, shows for the first time how the mean global physical parameters…
Multicolour photometry of the M0V+M5V eclipsing binary V405 And
K. Vida, K. Olah, Zs. Kovari +1
We present multicolour photometry and modelling of the active eclipsing binary star V405 And. The components of 0.2 and 0.5 solar masses are just below and above the theoretical li…
An extensive photometric study of the Blazhko RR Lyrae star MW Lyr: I. Light curve solution
J. Jurcsik, Á. Sódor, Zs. Hurta +10
We have obtained the most extensive and most accurate photometric data of a Blazhko variable MW Lyr during the 2006-2007 observing seasons. The data within each 0.05 phase bin of t…
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…
Surface velocity network with anti-solar differential rotation on the active K-giant Geminorum
Zs. Kõvári, J. Bartus, M. Švanda +4
We demonstrate the power of the local correlation tracking technique on stellar data for the first time. We recover the spot migration pattern of the long-period RS CVn-type binary…
