X-ray Variability and Photosphere Evolution during Accretion Disk Formation in Tidal Disruption Events
Xiaoshan Huang, Maria Renee Meza, Sol Bin Yun +3
The early time emission in tidal disruption events (TDEs) originates from both accretion and shocks, producing photons that eventually emerge from an inhomogeneous photosphere. We…
Radiation Hydrodynamic Simulations of Low-Energy Explosions of Red and Yellow Supergiants
Andrea Antoni, Yan-Fei Jiang, Eliot Quataert
A variety of physical processes leads to the low-energy ejection of material from the hydrogen-rich envelopes of red and yellow supergiants. These include common envelope events, s…
A Parameter Survey of Neutron Star Accretion Column Simulations
Lizhong Zhang, Omer Blaes, Yan-Fei Jiang
We conduct a parameter survey of neutron star accretion column simulations by solving the relativistic radiation MHD equations with opacities that account for strong magnetic field…
Magnetosonic Waves as a Driver of Observed Temperature Fluctuation Patterns in AGN Accretion Disks
Ish Kaul, Omer Blaes, Yan-Fei Jiang +1
Recent observations have revealed slow, coherent temperature fluctuations in AGN disks that propagate both inward and outward at velocities of , a kind of variabi…
Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: I. Survey of Eddington Ratios
Lizhong Zhang, James M. Stone, Patrick D. Mullen +3
We summarize results from a survey of radiation-dominated black hole accretion flows across a wide range of mass accretion rates, as well as two values of black hole spin and initi…
Radiation and Magnetic Pressure Support in Accretion Disks around Supermassive Black Holes and The Physical Origin of the Extreme Ultraviolet to Soft X-ray Spectrum
Yan-Fei Jiang, Omer Blaes, Ish Kaul +1
We present the results of four three-dimensional radiation magnetohydrodynamic simulations of accretion disks around a solar mass black hole, which produce the far ultraviol…
Non-Stationary Discs and Instabilities
Omer Blaes, Yan-Fei Jiang, Jean-Pierre Lasota +1
We review our current knowledge of thermal and viscous instabilities in accretion discs around compact objects. We begin with classical disc models based on analytic viscosity pres…
