Oscillations of General Relativistic Multi-fluid/Multi-layer Compact Stars
Lap-Ming Lin, N. Andersson, G. L. Comer
We develop the formalism for determining the quasinormal modes of general relativistic multi-fluid compact stars in such a way that the impact of superfluid gap data can be assesse…
On the stability of precessing superfluid neutron stars
K. Glampedakis, N. Andersson, D. I. Jones
We discuss a new superfluid instability occuring in the interior of mature neutron stars with implications for freely precessing neutron stars. This short-wavelength instability is…
Are neutron stars with crystalline colour superconducting cores interesting for the LIGO experiment?
B. Haskell, N. Andersson, D. I. Jones +1
We estimate the maximal deformation that can be sustained by a rotating neutron star with a crystalline colour superconducting quark core. Our results suggest that current gravitat…
Waves and instabilities in dissipative rotating superfluid neutron stars
T. Sidery, N. Andersson, G. L. Comer
We discuss wave propagation in rotating superfluid neutron star cores, taking into account the vortex mediated mutual friction force. For models where the two fluids co-rotate in t…
Modelling magnetically deformed neutron stars
B. Haskell, L. Samuelsson, K. Glampedakis +1
Rotating deformed neutron stars are important potential sources for groundbased gravitational-wave interferometers such as LIGO, GE0600 and VIRGO. One mechanism that may lead to si…
A characteristic approach to the quasi-normal mode problem
Lars Samuelsson, Nils Andersson, Asimina Maniopoulou
In this paper we discuss a new approach to the quasinormal-mode problem in general relativity. By combining a characteristic formulation of the perturbation equations with the inte…
