VAST: An ASKAP Survey for Variables and Slow Transients
Tara Murphy, Shami Chatterjee, David L. Kaplan +36
The Australian Square Kilometre Array Pathfinder (ASKAP) will give us an unprecedented opportunity to investigate the transient sky at radio wavelengths. In this paper we present V…
Thin accretion discs around millisecond X-ray pulsars
Solomon Belay Tessema, Ulf Torkelsson
Millisecond x-ray pulsars have weak magnetic dipole moments of \,T\,m compared to ordinary X-ray pulsars with dipole moments of \,T\,m. For this reas…
The structure of thin accretion discs around magnetised stars
Solomon Belay Tessema, Ulf Torkelsson
Aims: We determine the steady-state of an axisymmetric thin accretion disc with an internal dynamo around a magnetised star. Methods: Starting from the vertically integrated equati…
Oscillations of tori in the pseudo-Newtonian potential
Eva Sramkova, Ulf Torkelsson, Marek A. Abramowicz
Context. The high-frequency quasi-periodic oscillations (HF QPOs) in neutron star and stellar-mass black hole X-ray binaries may be the result of a resonance between the radial and…
Epicyclic Oscillations of Fluid Bodies: Newtonian Nonslender Torus
Omer M. Blaes, Eva Sramkova, Marek A. Abramowicz +2
We study epicyclic oscillations of fluid tori around black holes (in the Paczynski-Wiita potential) and derive exact analytic expressions for their radial and vertical eigenfrequen…
Propagation of non-linear circularly polarised Alfven waves in a homogeneous medium
Rim Turkmani, Ulf Torkelsson
We study the evolution of non-linear circularly polarised Alfven waves by solving numerically the time-dependent equations of magnetohydrodynamics (MHD) in one dimension. We examin…
