A magnetar formation in binary neutron star merger
Kenta Kiuchi, Alexis Reboul-Salze, Yuichiro Sekiguchi +1
We conduct a global general relativistic neutrino-radiation-transfer magnetohydrodynamics simulation of a - binary neutron star with the unprecedented spatial re…
Probing millisecond magnetar formation in binary neutron star mergers through X-ray follow-up of gravitational wave alerts
Clara Plasse, Alexis Reboul-Salze, Jérome Guilet +5
The nature of the remnant of a binary neutron star (BNS) merger is uncertain. Though certainly a black hole (BH) in the cases of the most massive BNSs, X-ray lightcurves from gamma…
Coexisting Tayler instability-driven dynamos in radiative zones: New dynamo solution and its impacts on stellar physics
Paul Barrère, Alexis Reboul-Salze, Patrick Eggenberger +4
Recent asteroseismic observations constitute a great challenge for rotating stellar evolution models, which predict overly fast internal rotation rates when only hydrodynamic proce…
Planetary Dynamos in Evolving Cold Gas Giants
Albert Elias-López, Fabio Del Sordo, Daniele Viganò +4
Magnetic fields remain one of the least understood aspects of exoplanetary systems. A deeper understanding of planetary dynamos and the evolution of surface magnetic properties thr…
Non-linear saturation of gravito-inertial modes excited by tidal resonances in binary neutron stars
Alexis Reboul-Salze, Aurélie Astoul, Hao-Jui Kuan +1
During the last seconds of a binary neutron-star merger, the tidal force can excite stellar oscillation modes to large amplitudes. From the perspective of premerger electromagnetic…
MRI-driven dynamo at high Pm numbers
Alexis Reboul-Salze, Loren E. Held, Kenta Kiuchi
To power gamma-ray bursts and other high-energy events, large-scale magnetic fields are required to extract rotational energy from compact objects such as black holes and neutron s…
