Abstract

The observations of supernovae (SNe) Ic occurring after the prompt emission of long gamma-ray bursts (GRBs) are addressed within the binary-driven hypernova (BdHN) model where GRBs originate from a binary composed of a 10M\sim10M_\odot carbon-oxygen (CO) star and a neutron star (NS). The CO core collapse gives the trigger, leading to a hypernova with a fast-spinning newborn NS (ν\nuNS) at its center. The evolution depends strongly on the binary period, PbinP_{\rm bin}. For Pbin5P_{\rm bin}\sim5min, BdHNe I occur with energies 105210^{52}--105410^{54}erg. The accretion of SN ejecta onto the NS leads to its collapse, forming a black hole (BH) originating the MeV/GeV radiation. For Pbin10P_{\rm bin}\sim 10min, BdHNe II occur with energies 105010^{50}--105210^{52}erg and for PbinP_{\rm bin}\simhours, BdHN III occurs with energies below 105010^{50}erg. {In BdHNe II and III,} no BH is formed. The 11--10001000ms ν\nuNS originates, in all BdHNe, the X-ray-optical-radio afterglows by synchrotron emission. The hypernova follows an independent evolution, becoming an SN Ic, powered by nickel decay, observable after the GRB prompt emission. We report 2424 SNe Ic associated with BdHNe. Their optical peak luminosity and time of occurrence are similar and independent of the associated GRBs. {From previously identified 380380 BdHN I comprising redshifts up to z=8.2z=8.2, we analyze} four examples with their associated hypernovae. By multiwavelength extragalactic observations, we identify seven new Episodes, theoretically explained, fortunately not yet detected in galactic sources, opening new research areas. Refinement of population synthesis simulations is needed to map the progenitors of such short-lived binary systems inside our galaxy.
