Time series analysis of bright TESS RRc stars: Additional modes, phase variations and more
J. M. Benkő, E. Plachy, H. Netzel +3
Using two years of data from the TESS space telescope, we have investigated the time series of 633 overtone pulsating field RR Lyrae (RRc) stars. The majority of stars (82.8 per ce…
A low-luminosity core-collapse supernova very similar to SN 2005cs
Zoltán Jäger, József Vinkó, Barna I. Bíró +5
We present observations and analysis of PSN J17292918+7542390, a low-luminosity Type II-P supernova (LL SN IIP). The observed sample of such events is still low, and their nature i…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
First observations of W Virginis stars with K2: detection of period doubling
E. Plachy, L. Molnár, M. I. Jurkovic +5
We present the first analysis of W Vir stars observed by the Kepler space telescope in the K2 mission. Clear cycle-to-cycle variation were detected in the light curves of KT Sco an…
Variable stars with the Kepler space telescope
László Molnár, Róbert Szabó, Emese Plachy
The Kepler space telescope has revolutionised our knowledge about exoplanets and stars and is continuing to do so in the K2 mission. The exquisite photometric precision, together w…
The Kepler Cepheid V1154 Cyg revisited: light curve modulation and detection of granulation
A. Derekas, E. Plachy, L. Molnar +8
We present a detailed analysis of the bright Cepheid-type variable star V1154 Cygni using 4 years of continuous observations by the Kepler space telescope. We detected 28 frequenci…
