Discovery of non-radial pulsations in the spectroscopic binary Herbig Ae star RS Cha
T. Böhm, W. Zima, C. Catala +3
In this article we present a first discovery of non radial pulsations in both components of the Herbig Ae spectroscopic binary star RS Cha. The binary was monitored in quasi-contin…
Close-up of primary and secondary asteroseismic CoRoT targets and the ground-based follow-up observations
K. Uytterhoeven, E. Poretti, M. Rainer +13
To optimise the science results of the asteroseismic part of the CoRoT satellite mission a complementary simultaneous ground-based observational campaign is organised for selected…
High-Precision Spectroscopy of Pulsating Stars
C. Aerts, S. Hekker, M. Desmet +4
We review methodologies currently available to interprete time series of high-resolution high-S/N spectroscopic data of pulsating stars in terms of the kind of (non-radial) modes t…
A new method for the spectroscopic identification of stellar non-radial pulsation modes. II. Mode identification of the Delta Scuti star FG Virginis
W. Zima, D. Wright, J. Bentley +7
We present a mode identification based on new high-resolution time-series spectra of the non-radially pulsating Delta Scuti star FG~Vir (HD 106384, V = 6.57, A5V). From 2002 Februa…
A new method for the spectroscopic identification of stellar non-radial pulsation modes. I. The method and numerical tests
W. Zima
We present the Fourier parameter fit method, a new method for spectroscopically identifying stellar radial and non-radial pulsation modes based on the high-resolution time-series s…
Inferences from pulsational amplitudes and phases for multimode Sct star FG Vir
J. Daszynska-Daszkiewicz, W. A. Dziembowski, A. A. Pamyatnykh +3
We combine photometric and spectroscopic data on twelve modes excited in FG Vir to determine their spherical harmonic degrees, , and to obtain constraints on the star model.…
