Early X-ray flares in GRBs

R Ruffini, Y Wang, Y Aimuratov… - The Astrophysical …, 2018 - iopscience.iop.org
We analyze the early X-ray flares in the GRB" flare–plateau–afterglow"(FPA) phase
observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the …

The morphology of the X-ray afterglows and of the jetted GeV emission in long GRBs

R Ruffini, R Moradi, JA Rueda, L Li… - Monthly Notices of …, 2021 - academic.oup.com
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 …

Evidence for the transition of a Jacobi ellipsoid into a Maclaurin spheroid in gamma-ray bursts

JA Rueda, R Ruffini, L Li, R Moradi, JF Rodriguez… - Physical Review D, 2022 - APS
In the binary-driven hypernova (BdHN) scenario, long gamma-ray bursts (GRBs) originate in
a cataclysmic event that occurs in a binary system composed of a carbon-oxygen (CO) star …

On the Ultra-relativistic Prompt Emission, the Hard and Soft X-Ray Flares, and the Extended Thermal Emission in GRB 151027A

R Ruffini, L Becerra, CL Bianco, YC Chen… - The Astrophysical …, 2018 - iopscience.iop.org
We analyze GRB 151027A within the binary-driven hypernova approach, with a progenitor
of a carbon–oxygen core on the verge of a supernova (SN) explosion and a binary …

[HTML][HTML] Thermal emission in the early afterglow of gamma-ray bursts from their interaction with supernova ejecta

R Ruffini, GV Vereshchagin, Y Wang - Astronomy & Astrophysics, 2017 - aanda.org
Context. A thermal X-ray component is observed in the early afterglow of some gamma-ray
bursts. Possible explanations include shockwave breakout, relativistic photosphere, or …

[PDF][PDF] On the universal GeV emission in binary-driven hypernovae and their inferred morphological structure

R Ruffini, R Moradi, Y Wang, Y Aimuratov… - arXiv preprint arXiv …, 2018 - researchgate.net
We address the significance of the observed GeV emission from Fermi-LAT on the
understanding of the structure of long GRBs. We examine 82 X-ray Flashs (XRFs), in none of …
