Asteroseismology of KIC 11754974: a high-amplitude SX Phe pulsator in a 343-day binary system
S. J. Murphy, A. Pigulski, D. W. Kurtz +13
The candidate SX Phe star KIC 11754974 shows a remarkably high number of combination frequencies in the Fourier amplitude spectrum: 123 of the 166 frequencies in our multi-frequenc…
Successful Asteroseismology for a Better Characterization of the Exoplanet HAT-P-7b
M. Oshagh, A. Grigahcène, O. Benomar +4
It is well known that asteroseismology is the unique technique permitting the study of the internal structure of pulsating stars using their pulsational frequencies, which is per s…
Pulsational amplitude growth of the star KIC 3429637 (HD 178875) in the context of Am and rho Puppis stars
Simon J. Murphy, A. Grigahcene, E. Niemczura +2
KIC 3429637 (HD 178875) is a delta Sct star whose light-curve shows continuous pulsational amplitude growth in Kepler Mission photometry. Analysis of the three largest amplitude pe…
Towards precise asteroseismology of solar-like stars
A. Grigahcène, M. -A. Dupret, S. G. Sousa +4
Adiabatic modeling of solar-like oscillations cannot exceed a certain level of precision for fitting individual frequencies. This is known as the problem of near surface effects on…
The excitation of solar-like oscillations in a delta Scuti star by efficient envelope convection
V. Antoci, G. Handler, T. L. Campante +21
Delta Scuti (delta Sct) stars are opacity-driven pulsators with masses of 1.5-2.5M, their pulsations resulting from the varying ionization of helium. In less massive star…
The Kepler characterization of the variability among A- and F-type stars. I. General overview
K. Uytterhoeven, A. Moya, A. Grigahcene +38
The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. We present a first general characterization of the…
