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…
Merger-inspired rotation laws and the low-T/W instability in neutron stars
Andrea Passamonti, Nils Andersson
Implementing a family of differential rotation laws inspired by binary neutron-star merger remnants, we consider the impact of the rotation profile on the low-T/W instability. We u…
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…
Towards asteroseismology of core-collapse supernovae with gravitational-wave observations - I. Cowling approximation
Alejandro Torres-Forné, Pablo Cerdá-Durán, Andrea Passamonti +1
Gravitational waves from core-collapse supernovae are produced by the excitation of different oscillation modes in the proto-neutron star (PNS) and its surroundings, including the…
