Magnetic Signatures in Merger Products
Nicolas Muntean, Lisa Bugnet, Lynn Buchele +5
Asteroseismic estimates of the magnetic field strength in the radiative interior of red giant stars depend strongly on the internal stellar structure derived from models. Since red…
Extending asteroseismic magnetometry across the diverse landscape of magnetic structures
Nicholas Z. Rui, J. M. Joel Ong, Armand Leclerc +5
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…
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…
Constraining the model-based uncertainties of asteroseismic magnetic field measurements in red giants
L. Buchele, L. Bugnet, N. Muntean +1
Magnetic fields inside red giants are measured using shifts to the oscillation frequencies. However, in the asymptotic framework, converting a frequency shift into a radial magneti…
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…
Magneto-Archeology of White Dwarfs. Revisiting the fossil field scenario with observational constraints during the red giant branch
Lukas Einramhof, Lisa Bugnet, Leila Magdalena Calcaferro +2
The detection of strong, large-scale magnetic fields at the surface of only the oldest population of white dwarfs might point towards a hidden internal magnetic field slowly rising…
