Impact of rotation on the amplitude of acoustic modes in solar-like stars: Insights from hydrodynamical simulations
Arthur Le Saux, Leïla Bessila, Stéphane Mathis
In solar-like stars, acoustic modes provide the main way of probing their internal structure and dynamics. Although these modes are expected to be ubiquitous in stars with convecti…
Twists in the flow: revisiting convective mixing in rotating stellar models. I. Effect on the stellar structure
Poojan Agrawal, Aaron Dotter, Conny Aerts +2
Convection and rotation are both key processes in stellar evolution modelling. While standard mixing-length theory (MLT) provides a widely used modelling of convection, it neglects…
Core-envelope coupling of gravito-inertial waves in pre-main-sequence solar-type stars
Sylvain N. Breton, Camilla Pezzotti, Stéphane Mathis +5
After the recent detection of solar equatorial Rossby waves, a renewed interest has been brought to the study of gravito-inertial waves propagating in the convective envelope of so…
The impact of differential rotation on the stochastic excitation of acoustic modes in solar-like pulsators
Gabriel Biscarrat, Leïla Bessila, Stéphane Mathis
Acoustic modes are excited by turbulent convection in the outer convective envelope of solar-like stars. Observational results from asteroseismic studies show that 44% of solar-lik…
A model of magnetised and rotating convection for stellar and planetary interiors
Leïla Bessila, Stéphane Mathis
Convection is a fundamental mechanism for energy transport in stars and planets, playing a pivotal role in shaping their structures and evolution. The Mixing-Length Theory, a monom…
The impact of rotation on the stochastic excitation of stellar acoustic modes in solar-like pulsators
Leïla Bessila, Adrien Deckx van Ruys, Valentin Buriasco +4
Recent observational results from asteroseismic studies show that an important fraction of solar-like stars do not present detectable stochastically excited acoustic oscillations.…
