Hydrodynamic Torques in Circumbinary Accretion Disks
Mackenzie S. L. Moody, Ji-Ming Shi, James M. Stone
Gaseous disks have been proposed as a mechanism for facilitating mergers of binary black holes. We explore circumbinary disk systems to determine the evolution of the central binar…
How bright are the gaps in circumbinary disk systems?
Ji-Ming Shi, Julian H. Krolik
When a circumbinary disk surrounds a binary whose secondary's mass is at least the primary's mass, a nearly empty cavity with radius a few times the binary sep…
Saturation of the magnetorotational instability in the unstratified shearing box with zero net flux: convergence in taller boxes
Ji-Ming Shi, James M. Stone, Chelsea X. Huang
Previous studies of the nonlinear regime of the magnetorotational instability in one particular type of shearing box model -- unstratified with no net magnetic flux -- find that wi…
Three Dimensional MHD Simulation of Circumbinary Accretion Disks -2. Net Accretion Rate
Ji-Ming Shi, Julian H. Krolik
When an accretion disk surrounds a binary rotating in the same sense, the binary exerts strong torques on the gas. Analytic work in the 1D approximation indicated that these torque…
Three Dimensional MHD Simulation of Circumbinary Accretion Disks: Disk Structures and Angular Momentum Transport
Ji-Ming Shi, Julian H. Krolik, Stephen H. Lubow +1
We present the first three-dimensional magnetohydrodynamic (MHD) simulations of a circumbinary disk surrounding an equal mass binary. The binary maintains a fixed circular orbit of…
What Is The Numerically Converged Amplitude of MHD Turbulence in Stratified Shearing Boxes?
Ji-Ming Shi, Julian H. Krolik, Shigenobu Hirose
We study the properties of the turbulence driven by the magnetorotational instability (MRI) in a stratified shearing box with outflow boundary conditions and an equation of state d…
