Description
In the binary-driven hypernova (BdHN) scenario, long gamma-ray bursts (GRBs) originate in a binary system composed of a carbon-oxygen (CO) star and a neutron star (NS) companion in close orbit. The collapse of the CO star generates a newborn NS ($\nu$NS) at its center and a type Ic supernova (SN) explosion. Part of the SN ejecta is accreted onto the NS companion and onto the $\nu$NS by fallback. The accretion process occurs at hypercritical (highly super-Eddington) rates, transferring mass and angular momentum to the stars. We here assess whether or not quark deconfinement can occur either in the $\nu$NS or in the NS companion during the hypercritical accretion process.
