On the oscillations of dissipative superfluid neutron stars
N. Andersson, K. Glampedakis, B. Haskell
We investigate the oscillations of slowly rotating superfluid stars, taking into account the vortex mediated mutual friction force that is expected to be the main damping mechanism…
Do superfluid instabilities prevent neutron star precession?
K. Glampedakis, N. Andersson, D. I. Jones
We discuss short wavelength (inertial wave) instabilities present in the standard two-fluid neutron star model when there is sufficient relative flow along the superfluid neutron v…
Modelling the dynamics of superfluid neutron stars
N. Andersson
In this brief summary I describe our recent work on superfluid neutron star dynamics. I review results on shear viscosity, hyperon bulk viscosity, vortex mediated mutual friction a…
How viscous is a superfluid neutron star core?
N. Andersson, G. L. Comer, K. Glampedakis
We discuss the effects of superfluidity on the shear viscosity in a neutron star core. Our study combines existing theoretical results for the viscosity coefficients with data for…
Modelling the spin equilibrium of neutron stars in LMXBs without gravitational radiation
N. Andersson, K. Glampedakis, B. Haskell +1
In this paper we discuss the spin-equilibrium of accreting neutron stars in LMXBs. We demonstrate that, when combined with a naive spin-up torque, the observed data leads to inferr…
Lagrangian perturbation theory of nonrelativistic rotating superfluid stars
N. Andersson, G. L. Comer, K. Grosart
We develop a Lagrangian perturbation framework for rotating non-relativistic superfluid neutron stars. This leads to the first generalization of classic work on the stability prope…
