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…
Superfluid neutron star turbulence
N. Andersson, T. Sidery, G. L. Comer
We analyse the implications of superfluid turbulence for neutron star physics. We begin by extending our previous results for the mutual friction force for a straight vortex array…
Mutual Friction in Superfluid Neutron Stars
N. Andersson, T. Sidery, G. L. Comer
We discuss vortex-mediated mutual friction in the two-fluid model for superfluid neutron star cores. Our discussion is based on the general formalism developed by Carter and collab…
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…
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…
Inertial modes of non-stratified superfluid neutron stars
R. Prix, G. L. Comer, N. Andersson
We present results concerning adiabatic inertial-mode oscillations of non-stratified superfluid neutron stars in Newtonian gravity, using the anelastic and slow-rotation approximat…
The superfluid two-stream instability and pulsar glitches
N. Andersson, G. L. Comer, R. Prix
This paper provides the first study of a new dynamical instability in superfluids. This instability is similar to the two-stream instability known to operate in plasmas. It is anal…
Are pulsar glitches triggered by a superfluid two-stream instability?
N. Andersson, G. L. Comer, R. Prix
Mature neutron stars are expected to have several superfluid components. Strong evidence for this is provided by the glitches that have been observed in dozens of pulsars. The unde…
Do Neutron Star Gravitational Waves Carry Superfluid Imprints?
G. L. Comer
Isolated neutron stars undergoing non-radial oscillations are expected to emit gravitational waves in the kilohertz frequency range. To date, radio astronomers have located about 1…
Slowly rotating superfluid Newtonian neutron star model with entrainment
R. Prix, G. L. Comer, N. Andersson
We develop a formalism to model slowly rotating superfluid Newtonian neutron stars. A two-fluid model is used to describe the matter, where one fluid is the superfluid neutrons tha…
On the dynamics of superfluid neutron star cores
N. Andersson, G. L. Comer
We discuss the nature of the various modes of pulsation of superfluid neutron stars using comparatively simple Newtonian models. The matter in these stars is described in terms of…
