Action based approach to dissipative relativistic fluid systems
G. L. Comer, N. Andersson, T. Celora +1
We develop an action principle for a relativistic two-fluid system with dissipation. The specific constituents of the model - which serves as a proof of principle - are particles a…
Impact of black hole spin on low-mass black hole-neutron star mergers
Rahime Matur, Ian Hawke, Nils Andersson
The recent detection of GW230529 suggests that black hole-neutron star mergers may involve low-mass black holes, potentially producing detectable electromagnetic counterparts. Moti…
Signatures of Low Mass Black Hole-Neutron Star Mergers
Rahime Matur, Ian Hawke, Nils Andersson
The recent observation of the GW230529 event indicates that black hole-neutron star binaries can contain low-mass black holes. Since lower mass systems are more favourable for tida…
Higher-level large-eddy filtering strategy for general relativistic fluid simulations
Thomas Celora, Nils Andersson, Ian Hawke +2
Nonlinear simulations of neutron star mergers are complicated by the need to represent turbulent dynamics. As we cannot (yet) perform simulations that resolve accurately both the g…
Covariant approach to relativistic large-eddy simulations: Lagrangian filtering
T. Celora, M. J. Hatton, I. Hawke +1
We present a proof-of-principle implementation of the first fully covariant filtering scheme applied to relativistic fluid turbulence. The filtering is performed with respect to sp…
The impact of nuclear reactions on the neutron-star g-mode spectrum
A. R. Counsell, F. Gittins, N. Andersson
Mature neutron stars are expected exhibit gravity g-modes due to stratification caused by varying composition. These modes are affected by nuclear reactions, leading to complex (da…
Modelling Neutron-Star Ocean Dynamics
F. Gittins, T. Celora, A. Beri +1
We re-visit the calculation of mode oscillations in the ocean of a rotating neutron star, which may be excited during thermonuclear X-ray bursts. Our present theoretical understand…
Local magneto-shear instability in Newtonian gravity
T. Celora, I. Hawke, N. Andersson +1
The magneto-rotational instability (MRI) - which is due to an interplay between a sheared background and the magnetic field - is commonly considered a key ingredient for developing…
Linearizing a Non-linear Formulation for General Relativistic Dissipative Fluids
Thomas Celora, Nils Andersson, Greg L. Comer
Fully non-linear equations of motion for dissipative general relativistic multi-fluids can be obtained from an action principle involving the explicit use of lower dimensional matt…
Crustal failure during binary inspiral
A. J. Penner, N. Andersson, D. I. Jones +2
We present the first fully relativistic calculations of the crustal strain induced in a neutron star by a binary companion at the late stages of inspiral, employing realistic equat…
