Tidal dissipation in magnetised, rotating stars and planets: linear calculations exploring various magnetic field configurations
Shijun Chu, Zhao Guo, Aurélie Astoul +2
We study tidal flows in the convective envelopes of rotating, magnetised fluid bodies, such as low-mass stars and giant planets. In well-mixed convective regions, (magneto-)inertia…

Tidal dissipation and spin-orbit alignment due to the precessional instability in convection zones in rotating giant planets and stars
Nils B. de Vries, Adrian J. Barker, Rainer Hollerbach
Tidal dissipation in star-planet systems occurs through various mechanisms, including the precessional instability. This is an instability of laminar flows (``Poincaré flows") for…

From proto-neutron star dynamo to low-field magnetars
Andrei Igoshev, Paul Barrère, Raphaël Raynaud +3
Low-field magnetars have dipolar magnetic fields that are 10-100 times weaker than the threshold, G, used to define classical magnetars, yet they produce simila…
