Abstract Recent observations of rapidly rotating stars have revealed the presence of regular patterns in their pulsation spectra. This has raised the question as to their physical origin, and, in particular, whether they can be explained by an asymptotic frequency formula for low-degree acoustic modes, as recently discovered through numerical calculations and theoretical considerations. In this context, a key question is whether compositional/density gradients can adversely affect such patterns…

Theoretical power spectra of mixed modes in low-mass red giant stars

Context. CoRoT and Kepler observations of red giant stars revealed very rich spectra of non-radial solar-like oscillations. Of particular interest was the detection of mixed modes that exhibit

Energetic study of solar-like oscillations in red giants

Observations of solar-like oscillations by CoRoT and Kepler space-borne telescopes, have opened new opportunities for the energetic modelling of these oscillations. In particular, oscillations



Asymptotic analysis of high-frequency acoustic modes in rapidly rotating stars

The asteroseismology of rapidly rotating pulsating stars is hindered by our poor knowledge of the effect of the rotation on the oscillation properties. Here we present an asymptotic analysis of

Regular patterns in the acoustic spectrum of rapidly rotating stars

Context: Rapid rotation modifies the structure of the frequency spectrum of pulsating stars, thus making mode identification difficult. Aims: We look for new forms of organisation for the frequency

Pulsation modes in rapidly rotating stellar models based on the self-consistent field method

Context. New observational means such as the space missions CoRoT and Kepler and ground-based networks are and will be collecting stellar pulsation data with unprecedented accuracy. A significant

Acoustic oscillations of rapidly rotating polytropic stars. I. Effects of the centrifugal distortion

Aims. A new non-perturbative method to compute accurate oscillation modes in rapidly rotating stars is presented. Methods. The effect of the centrifugal force is fully taken into account while the

Regular modes in rotating stars.

Comparisons with 2D numerical simulations of oscillations in polytropic stars show that both the frequency and amplitude distributions of these modes can accurately be described by an asymptotic theory for almost all rotation rates.

Self-consistent 2D models of fast-rotating early-type stars

Aims. This work aims at presenting the first two-dimensional model s of an isolated rapidly rotating star that include the deriv ation of the differential rotation and meridional circulation in a

Ab Initio Modelling of Steady Rotating Stars

Modelling isolated rotating stars at any rotation rate is a challenge for the next generation of stellar models. These models will couple dynamical aspects of rotating stars, like angular momentum

Detection of High-degree Prograde Sectoral Mode Sequences in the A-star KIC 8054146?

This paper examines the 46 frequencies found in the δ Sct star KIC 8054146 involving a frequency spacing of exactly 2.814 cycles day−1 (32.57 μHz), which is also a dominant low-frequency peak near or

Wave chaos in rapidly rotating stars.

The dynamics of acoustic rays in rotating polytropic stars are studied and it is shown using quantum chaos concepts that the eigenfrequency spectrum is a superposition of regular frequency patterns and an irregular frequency subset respectively associated with near-integrable and chaotic phase space regions.


Two years of Kepler data of KIC 8054146 (δ Sct/γ Dor hybrid) revealed 349 statistically significant frequencies between 0.54 and 191.36 cycles day−1 (6.3 μHz to 2.21 mHz). The 117 low frequencies
