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…
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.…
Impact of uniform rotation on the stochastic excitation of acoustic modes in solar-like oscillators
Leïla Bessila, Adrien Deckx Van Ruys, Valentin Buriasco +4
We evaluate the impact of the rotation on the stochastic excitation of acoustic (p) modes in solar-like pulsators. First, we derive the forced wave equation taking rotation into ac…
