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…
Discovery of the spectroscopic binary nature of the classical Cepheids FN Aql and V1344 Aql
L. Szabados, B. Cseh, J. Kovács +8
We present the analysis of photometric and spectroscopic data of two classical Cepheids, FN Aquilae and V1344 Aquilae. Based on the joint treatment of the new and earlier radial ve…
Medium-resolution echelle spectroscopy of pulsating variables and exoplanet host stars with sub-meter telescopes
J. Kovács, B. Csák, B. Cseh +5
Here we present two of our interesting results obtained over the last 18 months from spectroscopic monitoring of binary pulsating stars and exoplanet host stars. Our investigations…
Variability of M giant stars based on Kepler photometry: general characteristics
E. Bányai, L. L. Kiss, T. R. Bedding +15
M giants are among the longest-period pulsating stars which is why their studies were traditionally restricted to analyses of low-precision visual observations, and more recently,…
Spin-orbit resonance, transit duration variation and possible secular perturbations in KOI-13
Gy. M. Szabó, A. Pál, A. Derekas +3
KOI-13 is the first known transiting system exhibiting light curve distortions due to gravity darkening of the rapidly rotating host star. In this paper we analyze publicly availab…
Methods for exomoon characterisation: combining transit photometry and the Rossiter-McLaughlin effect
A. E. Simon, Gy. M. Szabó, K. Szatmáry +1
It has been suggested that moons around transiting exoplanets may cause observable signal in transit photometry or in the Rossiter-McLaughlin (RM) effect. In this paper a detailed…
