Probing the interior physics of stars through asteroseismology

C. Aerts

Summary: High-precision brightness measurements collected over years using telescopes in space have enabled astronomers to study the physics of stellar interiors through nonradial oscillations. The field of asteroseismology has provided new insights into how stars rotate and evolve chemically. Data-driven space asteroseismology has significantly improved computer models of star evolution, which are crucial for various research fields in space science and have potential applications in the search for extraterrestrial life and studies of supernova progenitors.

The effect of the centrifugal acceleration on period spacings of gravito-inertial modes in intermediate-mass stars

J. Henneco et al.

Summary: This study examines the effect of centrifugal acceleration on g modes and evaluates its detectability in space-based photometric observations. By implementing a new theoretical framework, the centrifugal deformation of pre-computed 1D spherical stellar structure models was calculated, and the corresponding g-mode frequencies were computed assuming uniform rotation. The results show that the centrifugal acceleration modifies the effect of the Coriolis acceleration on g modes and causes changes in pulsation periods and period spacings, which are detectable in modern space photometry and can improve asteroseismic modeling of centrifugally deformed stars.

Rotation of the convective core in γ Dor stars measured by dips in period spacings of g modes coupled with inertial modes

Hideyuki Saio et al.

Summary: The relation of period spacing versus period of dipole prograde g modes can be used to measure rotation rates in rapidly rotating gamma Dor and slowly pulsating B stars. By fitting the observed dips in period, the differential rotation of the convective core from the surrounding g-mode cavity can be inferred.

Internal mixing of rotating stars inferred from dipole gravity modes

May G. Pedersen et al.

Summary: Observations of 26 rotating stars with masses between 3 and 10 solar masses reveal a wide range of internal mixing levels, with models incorporating radially stratified mixing profiles showing the best asteroseismic performance. This study provides observational guidance for three-dimensional hydrodynamical simulations of transport processes in the deep interiors of stars, based on gravity modes probing the stars' deep interiors near the convective core. The internal mixing levels in the analyzed stars are unexpectedly varied and are best reproduced with models incorporating radially stratified mixing profiles.
