Beating and coupling in pulsating stars: A unified Fourier description and observational diagnostics
József M. Benkő, Emese Plachy
Long-term amplitude and phase variations in pulsating stars produce side peaks or multiplets in the Fourier spectrum of the light curves around the pulsation frequency and its harm…
Study of the Blazhko type RRc stars in the Stripe 82 region using SDSS and ZTF
Vaidehi Varma, Jozsef M. Benko, Chow-Choong Ngeow
RR Lyrae stars are pulsating stars, many of which also show a long-term variation called the Blazhko effect which is a modulation of amplitude and phase of the lightcurve. In this…
Frequency analysis of the first-overtone RR Lyrae stars based on the Extended Aperture Photometry from the K2 data
H. Netzel, L. Molnar, E. Plachy +1
Additional low-amplitude signals are observed in many RR Lyrae stars, beside the pulsations in radial modes. The most common ones are short-period signals forming a period ratio of…
Photometric and spectroscopic investigations of the Galactic field RRc candidates V764 Mon and HY Com
Jozsef M. Benko, Adam Sodor, Andras Pal
By analyzing photometric and spectroscopic time series in this paper, we show that the pulsator V764 Mon, assumed to be the brightest RR Lyrae star in the sky, is in fact a rapidly…
TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
Spectroscopic and photometric time series of the bright RRc star T Sex
J. M. Benkő, Á. Sódor, A. Pál
We present spectroscopic time series observations on one of the brightest northern RRc star, T Sex. Additionally, we also analysed extended photometric data sets, particularly the…
