Circumbinary Disks<br />
Newtonian Hydrodynamic Simulations:<br />
BBH exerts torque on gas via its time-varying mass quadrupole<br />
moment.<br />
BBH torque restores some of the accreting gas’ angular momentum,<br />
thereby diminishing the mass accretion rate through the gas.<br />
Surface density tends to build-up at r ∼ 2a as matter accretes faster<br />
beyond gap.<br />
Newtonian MHD Simulations:<br />
MHD torques seem to be able to accrete more material through the<br />
gap, but gap still exists.<br />
GRMHD Simulations in the post-Newtonian Regime (our project):<br />
Can MHD torques keep the disk/gap near the binary?<br />
What is the mass distribution in the inner disk? It is crucial for<br />
accurate EM models as emissivity typically scales as ρ n<br />
