We describe the afterglows of long gamma-ray-burst (GRB) within the context of a binary-driven hypernova (BdHN). In this paradigm afterglows originate from the interaction between a newly born neutron star ($\nu$NS), created by an Ic supernova (SN), and a mildly relativistic ejecta of a hypernova (HN). Such a HN in turn result from the impact of the GRB on the original SN Ic. The observed power-law afterglow in the optical and X-ray bands is shown to arise from the synchrotron emission of…

On the GeV Emission of the Type I BdHN GRB 130427A
We propose that the "inner engine" of a type I binary-driven hypernova (BdHN) is composed of a Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field $B_0$ aligned with
Induced Gravitational Collapse, Binary-Driven Hypernovae, Long Gramma-ray Bursts and Their Connection with Short Gamma-ray Bursts
There is increasing observational evidence that short and long Gamma-ray bursts (GRBs) originate in different subclasses, each one with specific energy release, spectra, duration, etc, and all of

On 2018 July 28, GRB 180728A triggered \textit{Swift} satellites and, soon after the determination of the redshift, we identified this source as a type II binary-driven hypernova (BdHN II) in our

The LIGO-Virgo Collaboration has announced the detection of GW170817 and has associated it with GRB 170817A . These signals have been followed after 11 hours by the optical and infrared emission of
Neutrino Oscillations Within the Induced Gravitational Collapse Paradigm of Long Gamma-Ray Bursts
The induced gravitational collapse (IGC) paradigm of long gamma-ray bursts (GRBs) associated with supernovae (SNe) predicts a copious neutrino-antineutrino ($\nu\bar{\nu}$) emission owing to the

Abstract We investigate the scenario of a binary system composed by a neutron star (NS) and a main sequence star which has been stripped to be a naked carbon-oxygen core (CO core). At a given time,
An Update of the Binary-Driven Hypernovae Scenario of Long Gamma-Ray Bursts
Abstract I discuss some most recent theoretical and observational results on the inner engine of the high-energy (GeV) emission of long gamma-ray bursts (GRBs), within the context of the

Neutrino Oscillations in Neutrino-Dominated Accretion Around Rotating Black Holes
In the binary-driven hypernova model of long gamma-ray bursts, a carbon–oxygen star explodes as a supernova in the presence of a neutron star binary companion in close orbit. Hypercritical (i.e.,
