Neutron Star Asteroseismology. Axial Crust Oscillations in the Cowling Approximation
Lars Samuelsson, Nils Andersson
Recent observations of quasi-periodic oscillations in the aftermath of giant flares in soft gamma-ray repeaters suggest a close coupling between the seismic motion of the crust aft…
Mountains on Neutron Stars: Accreted vs. Non-Accreted crusts
B. Haskell, D. I. Jones, N. Andersson
The aim of this paper is to compare the two cases of an isolated neutron star, with a non-accreted crust, and that of an accreting neutron star, with an accreted crust, and try to…
Ekman layer damping of r-modes revisited
Kostas Glampedakis, Nils Andersson
We investigate the damping of neutron star r-modes due to the presence of a viscous boundary (Ekman) layer at the interface between the crust and the core. Our study is motivated b…
Elastic or magnetic? A toy model for global magnetar oscillations with implications for QPOs during flares
Kostas Glampedakis, Lars Samuelsson, Nils Andersson
We use a simple toy-model to discuss global MHD modes of a neutron star, taking into account the magnetic coupling between the elastic crust and the fluid core. Our results suggest…
