The plunging region of thin accretion discs across the black hole spin range

Jake Rule, Andrew Mummery, Steven Balbus +2

We compute and test analytic models for the plunging region dynamics, thermodynamics, and magnetic fields against dedicated 3D global general relativistic magnetohydrodynamics (MHD…

Kinetic magnetohydrodynamics and Landau fluid closure in relativity

Abhishek Hegade K. R., James M. Stone

Diffuse accretion flows near a supermassive black hole are fundamentally weakly collisional. In such weakly collisional plasmas, the ion and electron distribution functions can dev…

Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: III. Near-Eddington Accretion

Lizhong Zhang, James M. Stone, Shane W. Davis +3

We present a comprehensive analysis of four near-Eddington black hole accretion models from GRMHD simulations with full radiation transport. This study investigates the dynamical e…

Mass Transport, Turbulent Mixing, and Inflow in Black Hole Accretion

George N. Wong, Lia Medeiros, James M. Stone

We investigate mass transport, mixing, and disk evolution in non-radiative black hole accretion flows using Lagrangian tracer particles embedded in general relativistic magnetohydr…

Radiation GRMHD Models of Accretion onto Stellar-Mass Black Holes: II. Super-Eddington Accretion

Lizhong Zhang, James M. Stone, Christopher J. White +3

We present a comprehensive analysis of super-Eddington black hole accretion simulations that solve the GRMHD equations coupled with angle-discretized radiation transport. The simul…

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…

The plunging region of a thin accretion disc around a Schwarzschild black hole

Jake Rule, Andrew Mummery, Steven Balbus +2

A set of analytic solutions for the plunging region thermodynamics have been developed recently under the assumption that the fluid undergoes a gravity-dominated geodesic plunge in…

Global Simulations of Gravitational Instability in Protostellar Disks with Full Radiation Transport II. Locality of Gravitoturbulence, Clumpy Spirals, and Implications for Observable Substructure

Wenrui Xu, Yan-Fei Jiang, Matthew W. Kunz +1

Spiral perturbations in a gravitationally unstable accretion disk regulate disk evolution through angular-momentum transport and heating and provide an observational signature of g…

Global Simulations of Gravitational Instability in Protostellar Disks with Full Radiation Transport. I. Stochastic Fragmentation with Optical-depth-dependent Rate and Universal Fragment Mass

Wenrui Xu, Yan-Fei Jiang, Matthew W. Kunz +1

Fragmentation in a gravitationally unstable accretion disk can be an important pathway for forming stellar/planetary companions. To characterize quantitatively the condition for an…

The three-dimensional structure of black hole accretion flows within the plunging region

Andrew Mummery, James M. Stone

We analyse, using new analytical models and numerical general relativistic magnetohydrodynamic simulations, the three-dimensional properties of accretion flows inside the plunging…

A Systematic Study of Planetary Envelope Growth with 3D Radiation-Hydrodynamics Simulations

Avery Bailey, Jim Stone, Jeffrey Fung

In the core accretion model of planet formation, envelope cooling regulates the accretion of material and ultimately sets the timescale to form a giant planet. Given the diversity…

A Global 3-D Simulation of Magnetospheric Accretion: I. Magnetically Disrupted Disks and Surface Accretion

Zhaohuan Zhu, James M. Stone, Nuria Calvet

We present a 3-D ideal MHD simulation of magnetospheric accretion onto a non-rotating star. The accretion process unfolds with intricate 3-D structures driven by various mechanisms…

Local Three-Dimensional Simulations of Magneto-Rotational Instability in Radiation-Dominated Accretion Disks

N. J. Turner, J. M. Stone, J. H. Krolik +1

We examine the small-scale dynamics of black hole accretion disks in which radiation pressure exceeds gas pressure. Local patches of disk are modeled by numerically integrating the…
