Multipolar magnetic configuration: a trace of post-mergers events in circumstellar disks around FS CMa Stars
A. Moranchel-Basurto, D. Kocakova, M. Cemeljic +3
Context: Observations suggest that magnetic fields of disk-bearing stars may have non-dipolar configurations. However, the influence of these configurations on magnetospheric accre…
Energy flow and radiation efficiency in radiative GRMHD simulations of neutron star ultraluminous X-ray sources
Fatemeh Kayanikhoo, WÅodek 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…
ULX collimation by outflows in moderately magnetized neutron stars
Fatemeh Kayanikhoo, WÅodek Kluźniak, Miljenko ÄemeljiÄ
We perform radiative magnetohydrodynamics simulations in general relativity (GRRMHD) of super-Eddington disk accretion onto neutron stars endowed with a magnetic dipole correspondi…
Pseudo-Newtonian simulation of a thin accretion disk around a Reissner-Nordström naked singularity
Miljenko ÄemeljiÄ, WÅodek Kluźniak, Ruchi Mishra +1
We present the first numerical simulations of a thin accretion disk around a Reissner-Nordström (RN) naked singularity (a charged point mass). The gravity of the RN naked singular…
