Self-Limited Accretion onto Embedded Binaries in a Uniform Medium
Marcus DuPont, Eliot Quataert
We study accretion from a uniform gas at rest onto equal-mass binaries -- the binary Bondi problem -- as a function of adiabatic index~ and compactness , where…

Strong Bow Shocks: Turbulence and An Exact Self-Similar Asymptotic
Marcus DuPont, Andrei Gruzinov, Andrew MacFadyen
We show that strong bow shocks are turbulent and non-universal near the head, but asymptote to a universal steady, self-similar, and analytically solvable flow in the downstream. T…

Did Binary Neutron Star Merger GW170817 Leave Behind A Long-lived Neutron Star?
Marcus DuPont, Andrew MacFadyen
We consider the observational implications of the binary neutron star (BNS) merger GW170817 leaving behind a rapidly rotating massive neutron star that launches a relativistic, equ…
