Magnetism in Massive Stars
Kyle C. Augustson
Massive stars are the drivers of star formation and galactic dynamics due to their relatively short lives and explosive demises, thus impacting all of astrophysics. Since they are…
Does magnetic field impact tidal dynamics inside the convective zone of low-mass stars along their evolution?
A. Astoul, S. Mathis, C. Baruteau +5
The dissipation of the kinetic energy of wave-like tidal flows within the convective envelope of low-mass stars is one of the key physical mechanisms that shapes the orbital and ro…
Probing the shape of the mixing profile and of the thermal structure at the convective core boundary through asteroseismology
Mathias Michielsen, May G. Pedersen, Kyle C. Augustson +2
Aims: We investigate from a theoretical perspective if space asteroseismology can be used to distinguish between different thermal structures and shapes of the near-core mixing pro…
Rossby and Magnetic Prandtl Number Scaling of Stellar Dynamos
K. ~C. Augustson, A. ~S. Brun, J. Toomre
Rotational scaling relationships are examined for the degree of equipartition between magnetic and kinetic energies in stellar convection zones. These scaling relationships are app…
Rotating Convection and Gravito-Inertial Wave Generation in Stellar Interiors
Kyle C. Augustson, Stéphane Mathis
Gravito-inertial waves can be excited at the interface of convective and radiative regions and by the Reynolds stresses in the bulk of the convection zone. The magnitude of their e…
A model of rotating convection in stellar and planetary interiors: I - convective penetration
Kyle C. Augustson, Stéphane Mathis
A monomodal model for stellar and planetary convection is derived for the magnitude of the rms velocity, degree of superadiabaticity, and characteristic length scale as a function…
