Equilibrium eccentricity of accreting binaries
Jonathan Zrake, Christopher Tiede, Andrew MacFadyen +1
Using high-resolution hydrodynamics simulations, we show that equal-mass binaries accreting from a circumbinary disk evolve toward an orbital eccentricity of , unles…

Gas-driven inspiral of binaries in thin accretion disks
Christopher Tiede, Jonathan Zrake, Andrew MacFadyen +1
Numerical studies of gas accretion onto supermassive black hole binaries (SMBHBs) have generally been limited to conditions where the circumbinary disk (CBD) is 10-100 times thicke…
