Complex dynamical regimes of the Tayler-Spruit dynamo
Paul Barrère, Paul Barrüre, Jérôme Guilet +2
Astrophysical dynamos feature various spatial structures and dynamical regimes, ranging from hemispherical magnetic fields to the random reversals of the geodynamo. The Tayler-Spru…
Coexisting Tayler instability-driven dynamos in radiative zones: New dynamo solution and its impacts on stellar physics
Paul Barrère, Alexis Reboul-Salze, Patrick Eggenberger +3
Recent asteroseismic observations constitute a great challenge for rotating stellar evolution models, which predict overly fast internal rotation rates when only hydrodynamic proce…
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…
Tayler-Spruit dynamo in binary neutron star merger remnants
Alexis Reboul-Salze, Paul Barrère, Kenta Kiuchi +4
In binary neutron star mergers, the remnant can be stabilized by differential rotation before it collapses into a black hole. Therefore, the angular momentum transport mechanisms a…
Tayler-Spruit dynamo in stably stratified rotating fluids: Application to proto-magnetars
Paul Barrère, Jérôme Guilet, Raphaël Raynaud +1
The formation of highly magnetized young neutron stars, called magnetars, is still a strongly debated question. A promising scenario invokes the amplification of the magnetic field…
Observational characterisation of large-scale transport and horizontal turbulent diffusivity in the quiet Sun
F. Rincon, P. Barrère, T. Roudier
The Sun is a magnetic star, and the only spatio-temporally resolved astrophysical system displaying turbulent MHD thermal convection. This makes it a privileged object of study to…
Numerical simulations of the Tayler-Spruit dynamo in proto-magnetars
Paul Barrère, Jérôme Guilet, Raphaël Raynaud +1
The Tayler-Spruit dynamo is one of the most promising mechanisms proposed to explain angular momentum transport during stellar evolution. Its development in proto-neutron stars spu…
A new scenario for magnetar formation: Tayler-Spruit dynamo in a proto-neutron star spun up by fallback
P. Barrère, J. Guilet, A. Reboul-Salze +2
Magnetars are isolated young neutron stars characterized by the most intense magnetic fields known in the universe. The origin of their magnetic field is still a challenging questi…
