KIC 2831097 - A 2-year orbital-period RR Lyrae binary candidate
Á. Sódor, M. Skarka, J. Liška +1
We report the discovery of a new Kepler first-overtone RR Lyrae pulsator, KIC 2831097. The pulsation shows large, 0.1 d amplitude, systematic phase variations that can be interpret…
The SERMON project: 48 new field Blazhko stars and an investigation of modulation-period distribution
Marek Skarka, Jiří Liška, Reinhold F. Auer +3
We investigated 1234 fundamental mode RR Lyrae stars observed by the All Sky Automated Survey (ASAS) to identify the Blazhko (BL) effect. A sample of 1547 BL stars from the literat…
Analysis of the multiple system with CP component phi Draconis
J. Liska
The star phi Dra comprises a spectroscopic binary and a third star that together form a visual triple system. It is one of the brightest chemically peculiar (CP) stars of the upper…
RR Lyrae stars in eclipsing systems - historical candidates
J. Liska, M. Skarka, P. Hajkova +1
Discovery of binary systems among RR Lyrae stars belongs to challenges of present astronomy. So far, none of classical RR Lyrae stars was clearly confirmed that it is a part of an…
