22 Mar 2001 | | Journal: | 2001, ESA SP--459, p. 227 | | Subject: | astro-ph | | Affiliation: | Instituto de Astronomia, UNAM), Jon Nix (University of Wisconsin, Madison) and Wlodzimierz Kluzniak (Copernicus Centre | | Abstract: | 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 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. | | Source: | arXiv, astro-ph/0103380 | | Services: | Forum | Review | PDF | Favorites | |
