Strange quark star II: the minimal and maximal gravitational mass and the Keplerian configuration
Fatemeh Kayanikhoo, Mateusz Kapusta, Miljenko ÄemeljiÄ +2
We employ the MIT bag model with density-dependent bag constant for the equation of state (EOS) to estimate the gravitational mass and Keplerian frequency of rapidly rotating stran…

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…
