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…
Near-core magnetic field strengths inferred from gravity modes in intermediate-mass stars
Oliver Durfeldt-Pedros, Victoria Antoci, Daniel Lecoanet +2
In this work, we derive upper limits for the strength of the near-core magnetic field in intermediate-mass stars, since high-order g-modes can be fully suppressed by a critical mag…
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…
Conversion and Damping of Nonaxisymmetric Internal Gravity Waves in Magnetized Stellar Cores
Cy S. David, Daniel Lecoanet, Pascale Garaud
Magnetism is thought to play an important role in the evolution and dynamics of stars, though little is known about magnetic fields deep within stellar interiors. A promising avenu…
Chemical transport by weakly nonlinear internal gravity waves in stars
Yifeng Mao, Daniel Lecoanet
While it is well-known that internal gravity waves (IGWs) transport chemicals in the radiative zones of stars, there remains substantial uncertainty on the amount of, and physical…
