GRB-SN Association within the Binary-Driven Hypernova Model
Y. Aimuratov, L. M. Becerra, C. L. Bianco +11
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…
Nature of the ultrarelativistic prompt emission phase of GRB 190114C
R. Moradi, J. A. Rueda, R. Ruffini +7
We address the physical origin of the ultrarelativistic prompt emission (UPE) phase of GRB 190114C observed in the interval 1.9-3.99 s, by the Fermi-GBM in 10 keV-10 MeV . Thanks t…
The morphology of the X-ray afterglows and of the jetted GeV emission in long GRBs
R. Ruffini, R. Moradi, J. A. Rueda +14
We recall evidence that long gamma-ray bursts (GRBs) have binary progenitors and give new examples. Binary-driven hypernovae (BdHNe) consist of a carbon-oxygen core (CO$_{\rm core}…
Self-similarity and power-laws in GRB 190114C
R. Ruffini, Liang Li, R. Moradi +10
Following Fermi and NOT observations, Ruffini et al. (2019b) soon identified GRB 190114C as BdHN I at z=0.424, it has been observed since, with unprecedented accuracy, [...] all th…
On the GeV emission of the type I BdHN GRB 130427A
R. Ruffini, R. Moradi, J. A. Rueda +9
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…
The inner engine of GeV-radiation-emitting gamma-ray bursts
R. Ruffini, J. A. Rueda, R. Moradi +12
We motivate how the most recent progress in the understanding the nature of the GeV radiation in most energetic gamma-ray bursts (GRBs), the binary-driven hypernovae (BdHNe), has l…
On the last stable orbit around rapidly rotating neutron stars
Federico Cipolletta, Christian Cherubini, Simonetta Filippi +2
We compute the binding energy and angular momentum of a test-particle at the last stable circular orbit (LSO) on the equatorial plane around a general relativistic, rotating neutro…
GRB 090510: a genuine short-GRB from a binary neutron star coalescing into a Kerr-Newman black hole
R. Ruffini, M. Muccino, Y. Aimuratov +9
In a new classification of merging binary neutron stars (NSs) we separate short gamma-ray bursts (GRBs) in two sub-classes. The ones with erg coalesce to f…
On the rate and on the gravitational wave emission of short and long GRBs
R. Ruffini, J. Rodriguez, M. Muccino +13
On the ground of the large number of gamma-ray bursts (GRBs) detected with cosmological redshift, we classified GRBs in seven subclasses, all with binary progenitors originating gr…
pair creation by vacuum polarization around electromagnetic black holes
C. Cherubini, A. Geralico, J. Rueda +1
The concept of "dyadotorus" was recently introduced to identify in the Kerr-Newman geometry the region where vacuum polarization processes may occur, leading to the creation of $e^…
