2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/2601We 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 initially represented by 17,000 particles modeling a self-gravitating fluid with the equation of state P= (rho - rho0)c**2/3, and the black hole by a point mass with an absorbing boundary at the Schwarzschild radius. As in similar calculations carried out for a stiff polytrope, the stellar core survives the initial episode of mass transfer, but here an accretion disk is clearly formed as well.3 pages, to appear in the proceedings of the 4th INTEGRAL workshop, "Exploring the extreme universe", Alicante, September 2000.
