Determining the metallicity of the solar envelope using seismic inversion techniques
Gaël Buldgen, S. J. A. J. Salmon, A. Noels +3
The solar metallicity issue is a long-lasting problem of astrophysics, impacting multi- ple fields and still subject to debate and uncertainties. While spectroscopy has mostly been…
Stellar acoustic radii, mean densities and ages from seismic inversion techniques
Gaël Buldgen, Daniel Roy Reese, Marc-Antoine Dupret +1
Context. Determining stellar characteristics such as the radius, the mass or the age is crucial when studying stellar evolution, exoplanetary systems or characterising stellar popu…
Are the stars of a new class of variability detected in NGC~3766 fast rotating SPB stars?
S. J. A. J. Salmon, J. Montalbán, D. R. Reese +2
A recent photometric survey in the NGC~3766 cluster led to the detection of stars presenting an unexpected variability. They lie in a region of the Hertzsprung-Russell (HR) diagram…
The puzzling new class of variable stars in NGC 3766 : old friend pulsators?
S. J. A. J. Salmon, J. Montalbàn, D. R. Reese +2
The recent variability survey of the NGC 3766 cluster revealed a considerable number of periodic variable stars in a region of the H-R diagram where no pulsation is expected. This…
Regular Oscillation Sub-spectrum of Rapidly Rotating Stars
Michael Pasek, François Lignières, Bertrand Georgeot +1
We present an asymptotic theory that describes regular frequency spacings of pressure modes in rapidly rotating stars. We use an asymptotic method based on an approximate solution…
On the interpretation of echelle diagrams for solar-like oscillations. Effect of centrifugal distortion
J. C. Suárez, M. J. Goupil, D. R. Reese +4
This work aims at determining the impact of slow to moderate rotation on the regular patterns often present in solar-like oscillation spectra. We focus on the well-known asteroseis…
