Mode Mixing and Rotational Splittings: I. Near-Degeneracy Effects Revisited
J. M. Joel Ong, Lisa Bugnet, Sarbani Basu
Rotation is typically assumed to induce strictly symmetric rotational splitting into the rotational multiplets of pure p- and g-modes. However, for evolved stars exhibiting mixed m…
Magnetic signatures on mixed-mode frequencies. II. Period spacings as a probe of the internal magnetism of red giants
L. Bugnet
Theoretical works have looked into the various topologies and amplitudes, as well as the stability of the magnetic field that is expected to be present in the radiative interior of…
Radio Emission from Binary Ultracool Dwarf Systems
Melodie M. Kao, J. Sebastian Pineda
Well-characterized binary systems will provide valuable opportunities to study the conditions that are necessary for the onset of both auroral and non-auroral magnetospheric radio…
Detecting deep axisymmetric toroidal magnetic fields in stars. The traditional approximation of rotation for differentially rotating deep spherical shells with a general azimuthal magnetic field
Hachem Dhouib, Stéphane Mathis, Lisa Bugnet +2
Asteroseismology has revealed small core-to-surface rotation contrasts in stars in the whole HR diagram. This is the signature of strong transport of angular momentum (AM) in stell…
