Radiative MHD Simulations of Photon Bubbles in Radiation-Supported Magnetized Atmospheres of Neutron Stars with Isotropic Thomson Scattering
Lizhong Zhang, Omer Blaes, Yan-Fei Jiang
A major uncertainty in the structure and dynamics of magnetized, radiation pressure dominated neutron star accretion columns in X-ray pulsars and pulsating ultraluminous X-ray sour…
A characteristic optical variability timescale in astrophysical accretion disks
Colin J. Burke, Yue Shen, Omer Blaes +8
Accretion disks around supermassive black holes in active galactic nuclei produce continuum radiation at ultraviolet and optical wavelengths. Physical processes in the accretion fl…
Investigating lack of accretion disk eccentricity growth in a global 3D MHD simulation of a superhump system
Bryance Oyang, Yan-Fei Jiang, Omer Blaes
We present the results of a 3D global magnetohydrodynamic (MHD) simulation of an AM CVn system that was aimed at exploring eccentricity growth in the accretion disc self-consistent…
Magnetically Modified Spherical Accretion in GRMHD: Reconnection-Driven Convection and Jet Propagation
Sean M. Ressler, Eliot Quataert, Christopher J. White +1
We present 3D general relativistic magnetohydrodynamic(GRMHD) simulations of zero angular momentum accretion around a rapidly rotating black hole, modified by the presence of initi…
