Nonlinear hydrodynamics in spinning neutron stars: Theoretical universal relations and equilibrium solutions
Hang Yu, Giorgio Nicolini, Shu Yan Lau +6
We study tides during the inspiral of a binary neutron star system, including nonlinear hydrodynamical interactions. Using an affine approximation that treats the perturbed neutron…
A variational approach to relativistic superfluid vortex elasticity
N. Andersson, S. Wells, G. L. Comer
It is well known that a superfluid rotates by forming an array of quantized vortices. A relativistic formulation for superfluid vortex dynamics is required for a range of problems…
The g-mode spectrum of reactive neutron star cores
N. Andersson, P. Pnigouras
We discuss the impact of nuclear reactions on the spectrum of gravity g-modes of a mature neutron star, demonstrating the anticipated disappearance of these modes when the timescal…
Beyond ideal magnetohydrodynamics: From fibration to 3+1 foliation
N. Andersson, I. Hawke, K. Dionysopoulou +1
We consider a resistive multi-fluid framework from the 3+1 space-time foliation point-of-view, paying particular attention to issues relating to the use of multi-parameter equation…
Quantised vortices and mutual friction in relativistic superfluids
N. Andersson, S. Wells, J. A. Vickers
We consider the detailed dynamics of an array of quantised superfluid vortices in the framework of general relativity, as required for quantitative modelling of realistic neutron s…
A covariant action principle for dissipative fluid dynamics: From formalism to fundamental physics
N. Andersson, G. L. Comer
We present a new variational framework for dissipative general relativistic fluid dynamics. The model extends the convective variational principle for multi-fluid systems to accoun…
