Strongly Magnetized Super-Eddington Accretion: How Spin and Accretion Rate Regulate Energy Output and Mass Loss
Tom Man Kwan, Lixin Dai, Cheuk Kwan Kan +5
Strongly magnetized super-Eddington accretion flows power many important astrophysical systems, but how black hole parameters control their output is unclear. We present 32 general…
The nature of tilted supercritical accretion discs
P. Chris Fragile, Matthew J. Middleton, Brooks Brasseur +2
In this paper, we report on the first 3D general relativistic radiation magnetohydrodynamic simulations of large supercritical accretion discs that are tilted with respect to the b…
Angle-dependent hardening of the reprocessed spectra in ULXs powered by accretion onto neutron stars
Sricheta Karmakar, Alexander A. Mushtukov, Matthew Middleton
It is anticipated that mass accretion rates exceeding approximately in X-ray pulsars lead to radiation-driven outflows from super-critical accretion disc…
GR-RMHD Simulations of Super-Eddington Accretion Flows onto a Neutron Star with Dipole and Quadrupole Magnetic Fields
Akihiro Inoue, Ken Ohsuga, Hiroyuki R. Takahashi +2
Although ultraluminous X-ray pulsars (ULXPs) are believed to be powered by super-Eddington accretion onto a magnetized neutron star (NS), the detailed structures of the inflow-outf…
