Radiative GRMHD simulations of puffy accretion discs: Numerical versus analytical models of sub-Eddington accretion
Debora Lančová, Maciek Wielgus, Marek Abramowicz +6
A widely accepted picture of an accretion flow in the luminous soft spectral state of X-ray binary systems is a geometrically thin disc structure much like the classic analytic sol…
Energy flow and radiation efficiency in radiative GRMHD simulations of neutron star ultraluminous X-ray sources
Fatemeh Kayanikhoo, Włodek Kluźniak, David Abarca +1
We investigate numerically the energy flow and radiation efficiency of accreting neutron stars as potential ultraluminous X-ray sources (ULXs). We perform ten simulations {in radia…
Observational properties of puffy disks: radiative GRMHD spectra of mildly sub-Eddington accretion
Maciek Wielgus, Debora Lancova, Odele Straub +7
Numerical general relativistic radiative magnetohydrodynamic simulations of accretion disks around a stellar mass black hole with a luminosity above 0.5 of the Eddington value reve…
Beamed emission from a neutron-star ULX in a GRRMHD simulation
David Abarca, Kyle Parfrey, Włodek Kluźniak
We perform a global 2.5D general-relativistic radiation magnetohydrodynamic simulation of super-critical accretion onto a neutron star with a G dipolar magnetic f…
Puffy accretion disks: sub-Eddington, optically thick, and stable
Debora Lančová, David Abarca, Włodek Kluźniak +6
We report on a new class of solutions of black hole accretion disks that we have found through three-dimensional, global, radiative magnetohydrodynamic simulations in general relat…
Atmospheric oscillations provide simultaneous measurement of neutron star mass and radius
D. A. Bollimpalli, M. Wielgus, D. Abarca +1
Neutron stars with near-Eddington observable luminosities were shown to harbor levitating atmospheres, suspended above their surface. We report a new method to simultaneously measu…
