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…
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…
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…
The impact of differential rotation on the stochastic excitation of acoustic modes in solar-like stars
Gabriel Biscarrat, Leïla Bessila, Stéphane Mathis
We model the stochastic excitation of acoustic modes in solar-like pulsators taking into account the action of differential rotation. We derive the theoretical formalism for the st…
The 2D dynamics of radiative zones of low-mass stars
D. Hypolite, S. Mathis, M. Rieutord
In the context of secular evolution, we describe the dynamics of the radiative core of low-mass stars to understand the internal transport of angular momentum in such stars which r…
Lithium abundance and rotation of seismic solar analogues - Solar and stellar connection from Kepler and Hermes observations
P. G. Beck, J. -D. do Nascimento, T. Duarte +13
Lithium abundance A(Li) and surface rotation are good diagnostic tools to probe the internal mixing and angular momentum transfer in stars. We explore the relation between surface…
Probing seismic solar analogues through observations with the NASA Kepler space telescope and HERMES high-resolution spectrograph
P. G. Beck, D. Salabert, R. A. García +21
Stars similar to the Sun, known as solar analogues, provide an excellent opportunity to study the preceding and following evolutionary phases of our host star. The unprecedented qu…
Impact of rotation on the geometrical configurations of fossil magnetic fields
Constance Emeriau, Stéphane Mathis
The MiMeS project demonstrated that a small fraction of massive stars (around 7%) presents large-scale, stable, generally dipolar magnetic fields at their surface. They are suppose…
CP and related phenomena in the context of Stellar Evolution
J. Braithwaite, T. Akgün, E. Alecian +13
We review the interaction in intermediate and high mass stars between their evolution and magnetic and chemical properties. We describe the theory of Ap-star `fossil' fields, befor…
