Asteroseismic imprints of strong non-axisymmetric fields in the cores of red giants

Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5

To date, magnetic fields have been asteroseismically measured in nearly one hundred red giant cores. However, most analyses assume weak magnetic fields and slow rotation so that pe…

Extending asteroseismic magnetometry across the diverse landscape of magnetic structures

Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +6

Magnetic fields have now been asteroseismically measured in the cores of many red giants. However, most interpretations of these measurements assume that the magnetic field is far…

Co-existence of Internal Gravity Waves and Tayler-Spruit Magnetic Fields in the Radiative Core of Low-mass Stars

L. Amard, S. Mathis

The Tayler-Spruit dynamo (TSD) is able to generate a small-scale magnetic field in the differentially rotating stably stratified layers of stars and was recently observed in numeri…

The inertial dip as a window on the convective core dynamics

Lucas Barrault, Lisa Bugnet, Stéphane Mathis +1

Gamma Dor stars are ideal targets for studies of the innermost dynamical properties of stars, due to their rich frequency spectrum of gravito-inertial modes propagating in the radi…

Exploring the probing power of gamma-Dor's inertial dip for core magnetism: case of a toroidal field

Lucas Barrault, Lisa Bugnet, Stéphane Mathis +1

Gamma-Dor stars are ideal targets for studies of stellar innermost dynamical properties due to their rich asteroseismic spectrum of gravity modes. Integrating internal magnetism to…
