Abstract The observed association of Long Gamma-Ray Bursts (LGRBs) with peculiar Type Ic supernovae gives support to Woosley‘s collapsar/hypernova model, in which the GRB is produced by the collapse of the rapidly rotating core of a massive star to a black hole. The association of LGRBs with small star-forming galaxies suggests low-metallicity to be a condition for a massive star to evolve to the collapsar stage. Both completely-mixed single star models and binary star models are possible. In… Expand

Evolution of Progenitor Stars of Type Ibc Supernovae and Long Gamma-Ray Bursts
Abstract We discuss how rotation and binary interactions may be related to the diversity of type Ibc supernovae and long gamma-ray bursts. After presenting recent evolutionary models of massiveExpand
Close binary progenitors of gamma-ray bursts
The strong dependence of the neutrino annihilation mechanism on the mass accretion rate makes it difficult to explain the long-duration gamma-ray bursts (LGRBs) with duration in excess of 100 s asExpand
An Argument for Weakly-Magnetized, Slowly-Rotating Progenitors of Long Gamma-Ray Bursts
Using binary evolution with Case-C mass transfer, the spins of several black holes (BHs) in X$-$ray binaries (XBs) have been predicted and confirmed (three cases) by observations. The rotationalExpand
Population synthesis of gamma-ray bursts with precursor activity and the spinar paradigm
We study statistical properties of long gamma-ray bursts (GRBs) produced by the collapsing cores of WR stars in binary systems. Fast rotation of the cores enables a two-stage collapse scenario,Expand
Gamma-ray bursts from tidally spun-up Wolf-Rayet stars?
Context. The collapsar model requires rapidly rotating Wolf-Rayet stars as progenitors of long gamma-ray bursts. However, Galactic Wolf-Rayet stars rapidly lose angular momentum due to their intenseExpand
Wolf–Rayet stars, black holes and the first detected gravitational wave source
Abstract The recently discovered burst of gravitational waves GW150914 provides a good new chance to verify the current view on the evolution of close binary stars. Modern population synthesis codesExpand
We investigate the evolution of Type Ib/c supernova (SN Ib/c) progenitors in close binary systems, using new evolutionary models that include the effects of rotation, with initial masses of 12-25 M ☉Expand
The Population of Helium-Merger Progenitors: Observational Predictions
The helium-merger gamma-ray burst progenitor is produced by the rapid accretion onto a compact remnant (neutron star or black hole) when it undergoes a common envelope inspiral with its companion'sExpand
Hypercritical Accretion, Induced Gravitational Collapse, and Binary-Driven Hypernovae
The induced gravitational collapse (IGC) paradigm has been successfully applied to the explanation of the concomitance of gamma-ray bursts (GRBs) with supernovae (SNe) Ic. The progenitor is a tightExpand
Can massive Be/Oe stars be progenitors of long gamma ray bursts?
Context. The identification of long-gamma-ray-bursts (LGRBs) is still uncertain, although the collapsar engine of fast-rotating massive stars is gaining a strong consensus. Aims. We propose thatExpand


Binary star progenitors of long gamma-ray bursts
Context. The collapsar model for long gamma-ray bursts requires a rapidly rotating Wolf-Rayet star as progenitor. Aims. We test the idea of producing rapidly rotating Wolf-Rayet stars in massiveExpand
Formation rates of core-collapse supernovae and gamma-ray bursts
Core collapse of massive stars with a relativistic jet expulsion along the rotation axis is a widely discussed scenario for gamma-ray burst (GRB) production. However the nature of the stellarExpand
The Progenitor stars of gamma-ray bursts
Those massive stars that give rise to gamma-ray bursts (GRBs) during their deaths must be endowed with an unusually large amount of angular momentum in their inner regions, 1-2 orders of magnitudeExpand
Helium Star/Black Hole Mergers: A New Gamma-Ray Burst Model
We present a model for gamma-ray bursts (GRBs) in which a stellar mass black hole acquires a massive accretion disk by merging with the helium core of its red giant companion. The black hole entersExpand
Gamma-ray bursts from stellar mass accretion disks around black holes
A cosmological model for gamma-ray bursts is explored in which the radiation is produced as a broadly beamed pair fireball along the rotation axis of an accreting black hole. The black hole may be aExpand

Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα 10 M☉, in which iron-core collapse does not produce a successful outgoingExpand
Evolution of rapidly rotating metal-poor massive stars towards gamma-ray bursts
Recent models of rotating massive stars including magnetic fields prove it difficult for the cores of single stars to retain enough angular momentum to produce a collapsar and gamma-ray burst. At lowExpand
The unusual afterglow of the γ-ray burst of 26 March 1998 as evidence for a supernova connection
Cosmic γ-ray bursts have now been firmly established as one of the most powerful phenomena in the Universe, releasing almost the rest-mass energy of a neutron star within the space of a few secondsExpand
A very energetic supernova associated with the γ-ray burst of 29 March 2003
Over the past five years evidence has mounted that long-duration (>2 s) γ-ray bursts (GRBs)—the most luminous of all astronomical explosions—signal the collapse of massive stars in our Universe. ThisExpand
Formation of massive black holes through runaway collisions in dense young star clusters
Numerical simulations of the evolution and motion of stars within the clusters find that for MGG 11 dynamical friction leads to the massive stars sinking rapidly to the centre of the cluster, where they participate in a runaway collision. Expand
