Accretion disk assembly and survival during the disruption of a neutron star by a black hole
Enrico Ramirez-Ruiz, William H. Lee
We study the formation of accretion disks resulting from dynamical three dimensional binary coalescence calculations, where a neutron star is tidally disrupted before being swallow…
Binary coalescence of a strange star with a black hole: Newtonian results
William H. Lee, Wlodzimierz Kluzniak, Jon Nix
We present Newtonian three-dimensional hydrodynamical simulations of the merger of quark stars with black holes. The initial conditions correspond to non-spinning stars in Kepleria…
Coalescence of a strange star with a black hole
William H. Lee, Jon Nix, Wlodzimierz Kluzniak
We present the first numerical results on the binary coalescence of a quark star with a black hole, obtained with a 3-D Newtonian smooth particle hydro (SPH) code. The star is init…
Advection dominated flows around black holes in two dimensions
William H. Lee
We show the results of two-dimensional, azimuthally symmetric simulations of advection dominated fluid flows around black holes. We use the SPH method, and the alpha-prescription f…
Hydrodynamics of black hole-neutron star coalescence
William H. Lee, Wlodzimierz Kluzniak
We present a numerical study of the hydrodynamics in the final stages of inspiral in a black hole-neutron star binary, when the separation becomes comparable to the stellar radius.…
Creation of a dense torus in the coalescence of a black hole with a neutron star
Wlodzimierz Kluzniak, William H. Lee
We used a newtonian SPH (smooth-particle hydrodynamics) code to follow the final stages of evolution of a coalescing binary system of a neutron star and a black hole. We find that…
