The force-free twisted magnetosphere of a neutron star - II: Degeneracies of the Grad-Shafranov equation
Taner Akgün, Pablo Cerdá-Durán, Juan Antonio Miralles +1
We extend our previous study of equilibrium solutions of non-rotating force-free magnetospheres of neutron stars. We show that multiple solutions exist for the same sets of paramet…
Long-term evolution of the force-free twisted magnetosphere of a magnetar
Taner Akgün, Pablo Cerdá-Durán, Juan Antonio Miralles +1
We study the long-term quasi-steady evolution of the force-free magnetosphere of a magnetar coupled to its internal magnetic field. We find that magnetospheric currents can be main…
On the magnetic field evolution timescale in superconducting neutron star cores
Andrea Passamonti, Taner Akgün, José Pons +1
We revisit the various approximations employed to study the long-term evolution of the magnetic field in neutron star cores and discuss their limitations and possible improvements.…
Evolution of a proto-neutron star with a nuclear many-body equation of state: Neutrino luminosity and gravitational wave frequencies
Giovanni Camelio, Alessandro Lovato, Leonardo Gualtieri +3
In a core-collapse supernova, a huge amount of energy is released in the Kelvin-Helmholtz phase subsequent to the explosion, when the proto-neutron star cools and deleptonizes as i…
