Dynamical tides in superfluid neutron stars
Andrea Passamonti, Nils Andersson, Pantelis Pnigouras
We study the tidal response of a superfluid neutron star in a binary system, focussing on Newtonian models with superfluid neutrons present throughout the star's core and the inner…
Dynamical tides in neutron stars: The impact of the crust
Andrea Passamonti, Nils Andersson, Pantelis Pnigouras
We consider the dynamical tidal response of a neutron star in an inspiralling binary, focussing on the impact of the star's elastic crust. Within the context of Newtonian gravity,…
Instabilities in neutron-star postmerger remnants
Xiaoyi Xie, Ian Hawke, Andrea Passamonti +1
Using nonlinear, fully relativistic, simulations we investigate the dynamics and gravitational-wave signature associated with instabilities in neutron star postmerger remnants. For…
Towards asteroseismology of core-collapse supernovae with gravitational-wave observations - II. Spacetime perturbations
Alejandro Torres-Forné, Pablo Cerdá-Durán, Andrea Passamonti +2
Improvements in ground-based, advanced gravitational wave (GW) detectors may allow in the near future to observe the GW signal of a nearby core-collapse supernova. For the most com…
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.…
The relevance of ambipolar diffusion for neutron star evolution
Andrea Passamonti, Taner Akgün, José A. Pons +1
We study ambipolar diffusion in strongly magnetised neutron stars, with special focus on the effects of neutrino reaction rates and the impact of a superfluid/superconducting trans…
Quasi-periodic oscillations in superfluid, relativistic magnetars with nuclear pasta phases
Andrea Passamonti, José A. Pons
We study the torsional magneto-elastic oscillations of relativistic superfluid magnetars and explore the effects of a phase transition in the crust-core interface (nuclear pasta) w…
Radiation drag in the field of a non-spherical source
Donato Bini, Andrea Geralico, Andrea Passamonti
The motion of a test particle in the gravitational field of a non-spherical source endowed with both mass and mass quadrupole moment is investigated when a test radiation field is…
The dynamics of pulsar glitches: Contrasting phenomenology with numerical evolutions
T. Sidery, A. Passamonti, N. Andersson
In this paper we consider a simple two-fluid model for pulsar glitches. We derive the basic equations that govern the spin evolution of the system from two-fluid hydrodynamics, acc…
