Explosive Combustion of a Neutron Star into a Quark Star: the non-premixed scenario
Rachid Ouyed, Brian Niebergal, Prashanth Jaikumar
We review aspects of the hydrodynamical combustion of nuclear matter to strange quark matter in a neutron star. Numerical studies on non-premixed combustion that consistently inclu…
SGR 0418+5729 as an evolved Quark-Nova compact remnant
Rachid Ouyed, Denis Leahy, Brian Niebergal
Soft gamma repeaters and anomalous X-ray pulsars are believed to be magnetars, i.e. neutron stars powered by extreme magnetic fields, B~10^(14)-10^(15) Gauss. The recent discovery…
Numerical Simulation of the Hydrodynamical Combustion to Strange Quark Matter
Brian Niebergal, Rachid Ouyed, Prashanth Jaikumar
We present results from a numerical solution to the burning of neutron matter inside a cold neutron star into stable (u,d,s) quark matter. Our method solves hydrodynamical flow equ…
Confronting 3 Dimensional Time-dependent Jet Simulations with HST Observations
Jan Staff, Brian Niebergal, Rachid Ouyed +2
We perform state-of-the-art, 3D, time-dependent simulations of magnetized disk winds, carried out to simulation scales of 60 Astronomical Units, in order to confront optical HST ob…
Vortex Dynamics in Color-Superconducting Quark stars: The Re-heating of Magnetars
Brian Niebergal, Rachid Ouyed, Rodrigo Negreiros +1
Compact stars made of quark matter rather than confined hadronic matter, are expected to form a color superconductor. This superconductor ought to be threaded with rotational vorte…
The Meissner Effect and Vortex Expulsion in Color-Superconducting Quark stars, and its Role for Re-heating of Magnetars
Brian Niebergal, Rachid Ouyed, Rodrigo Negreiros +1
Compact stars made of quark matter rather than confined hadronic matter, are expected to form a color superconductor. This superconductor ought to be threaded with rotational vorte…
