X-ray burst ignition location on the surface of accreting X-ray pulsars: Can bursts preferentially ignite at the hotspot?

Autor: Goodwin, A. J., Heger, A., Chambers, F. R. N., Watts, A. L., Cavecchi, Y.

Hotspots on the surface of accreting neutron stars have been directly observed via pulsations in the lightcurves of X-ray pulsars. They are thought to occur due to magnetic channelling of the accreted fuel to the neutron star magnetic poles. Some X-r

Thermal convection in rotating spherical shells: temperature-dependent internal heat generation using the example of triple-$\alpha$ burning in neutron stars

Autor: Garcia, F., Chambers, F. R. N, Watts, A. L.

Publikováno v: Phys. Rev. Fluids 3, 123501 (2018)

We present an extensive study of Boussinesq thermal convection including a temperature-dependent internal heating source, based on numerical three-dimensional simulations. The temperature dependence mimics triple-$\alpha$ nuclear reactions and the fl

Polar waves and chaotic flows in thin rotating spherical shells

Autor: Garcia, F., Chambers, F. R. N., Watts, A. L.

Publikováno v: Phys. Rev. Fluids 4, 074802 (2019)

Convection in rotating spherical geometries is an important physical process in planetary and stellar systems. Using continuation methods at low Prandtl number, we find both strong equatorially asymmetric and symmetric polar nonlinear rotating waves

Report

The onset of low Prandtl number thermal convection in thin spherical shells

Autor: Garcia, F., Chambers, F. R. N., Watts, A. L.

This study considers the onset of stress-free Boussinesq thermal convection in rotating spherical shells with aspect ratio $\eta=r_i/r_o=0.9$ ($r_i$ and $r_o$ being the inner and outer radius), Prandtl numbers ${\rm Pr} \in[10^{-4},10^{-1}]$, and Tay
