Stochastic excitation of non-radial modes I. High-angular-degree p modes
K. Belkacem, R. Samadi, M. J. Goupil +1
Turbulent motions in stellar convection zones generate acoustic energy, part of which is then supplied to normal modes of the star. Their amplitudes result from a balance between t…
Impact of the new solar abundances on the calibration of the PMS binary system RS Cha
E. Alecian, Y. Lebreton, M-J. Goupil +2
Context: In a recent work, we tried to obtain a calibration of the two components of the pre-main sequence binary system RS Cha by means of theoretical stellar models. We found tha…
An asteroseismic study of the beta Cephei star theta Ophiuchi: constraints on global stellar parameters and core overshooting
M. Briquet, T. Morel, A. Thoul +5
We present a seismic study of the beta Cephei star theta Ophiuchi. Our analysis is based on the observation of one radial mode, one rotationally split l = 1 triplet and three compo…
Multi-site observations of Delta Scuti stars 7 Aql and 8 Aql (a new Delta Scuti variable): The twelfth STEPHI campaign in 2003
L. Fox Machado, E. Michel, F. Perez Hernandez +12
We present an analysis of the pulsation behaviour of the Delta Scuti stars 7 Aql (HD 174532) and 8 Aql (HD 174589) -- a new variable star -- observed in the framework of STEPHI XII…
Effect of convective outer layers modeling on non-adiabatic seismic observables of delta Scuti stars
J. Montalban, M. -A. Dupret
The identification of pulsation modes in delta Scuti stars is mandatory to constrain the theoretical stellar models. The non-adiabatic observables used in the photometric identific…
Oscillating Blue Stragglers, gamma Doradus stars and eclipsing binaries in the open cluster NGC2506
T. Arentoft, J. De Ridder, F. Grundahl +9
This is the first step in a project to combine studies of eclipsing binaries and oscillating stars to probe the interior of Blue Stragglers (BS). This may imply a way to discrimina…
