The Burn-UD code for the numerical simulations of the Hadronic-to-Quark-Matter phase transition
Amir Ouyed, Luis Welbanks, Nico Koning +1
Burn-UD is a hydrodynamic combustion code used to model the phase transition of hadronic to quark matter with particular application to the interior of neutron stars. Burn-UD model…
A Spallation Model for 44Ti production in Core Collapse Supernovae
Amir Ouyed, Rachid Ouyed, Denis Leahy +1
Current cc-SN models predict overproduction of 44Ti compared to observations. We present a model for an alternative channel where a cc-SN explosion is followed by a neutron star de…
Quark Nova Signatures in Super-luminous Supernovae
Mathew Kostka, Nico Koning, Rachid Ouyed +2
Recent observational surveys have uncovered the existence of super-luminous supernovae (SLSNe). While several possible explanations have been put forth, a consensus description for…
Quark nova inside supernova: Application to GRBs and XROs
Jan Staff, Rachid Ouyed
In this paper we consider a quark nova occurring inside an exploding star. The quark nova ejecta will shock when interacting with the stellar envelope. When this shock reaches the…
Quark-Novae in Low-Mass X-ray Binaries with massive neutron stars: A universal model for short-hard Gamma-Ray Bursts
Rachid Ouyed, Jan E. Staff, Prashanth Jaikumar
We show that several features reminiscent of short-hard Gamma-ray Bursts (GRBs) arise naturally when Quark-Novae occur in low-mass X-ray binaries born with massive neutron stars (>…
