The r-modes of slowly rotating, stratified neutron stars
Fabian Gittins, Nils Andersson
The only r-modes that exist in a globally barotropic, rotating, Newtonian star are the fundamental solutions, where and are the indices of the spherical harmonic…
Formulating the r-mode problem for slowly rotating neutron stars
Nils Andersson, Fabian Gittins
We revisit the problem of inertial r-modes in stratified stars, drawing on a more precise description of the composition stratification in a mature neutron star. The results highli…
Building post-Newtonian neutron stars
Nils Andersson, Fabian Gittins, Shanshan Yin +1
Owed to their compactness, neutron stars involve strong gravity and extreme density physics. Nevertheless, at present, there are a variety of problems where progress (at least conc…
Rotating Love: The dynamical tides of spinning Newtonian stars
Pantelis Pnigouras, Fabian Gittins, Amlan Nanda +2
We carefully develop the framework required to model the dynamical tidal response of a spinning neutron star in an inspiralling binary system, in the context of Newtonian gravity,…
A covariant approach to relativistic large-eddy simulations: The fibration picture
Thomas Celora, Nils Andersson, Ian Hawke +1
Models of turbulent flows require the resolution of a vast range of scales, from large eddies to small-scale features directly associated with dissipation. As the required resoluti…
A gravitational-wave perspective on neutron-star seismology
N. Andersson
We provide a bird's-eye view of neutron-star seismology, which aims to probe the extreme physics associated with these objects, in the context of gravitational-wave astronomy. Focu…
