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…
Strange quark star I: the maximum gravitational mass and deformation of magnetized spinning model
Fatemeh Kayanikhoo, Mateusz Kapusta, Miljenko ÄemeljiÄ +1
We investigate the structural parameters of strange quark stars (SQS) under the influence of strong magnetic fields and varying rotational frequencies. The equation of state is com…
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…
