Numerical studies of primordial star formation suggest that the first stars in the universe may have been very massive. Stellar models indicate that non-rotating Population III stars with initial masses of 140-260 Msun die as highly energetic pair-instability supernovae. We present new two-dimensional simulations of primordial pair-instability supernovae done with the CASTRO code. Our simulations begin at earlier times than previous multidimensional models, at the onset of core collapse, to… 
Pair-Instability Supernovae of Fast Rotating Stars
We present 2D simulations of pair-instability supernovae considering rapid rotation during their explosion phases. Recent studies of the Pop III star formation suggested that these stars could be
Stellar Yields of Rotating First Stars. II. Pair Instability Supernovae and Comparison with Observations
Recent theory predicts that a first star is born with a massive initial mass of $\gtrsim$ 100 $M_\odot$. Pair instability supernova (PISN) is a common fate for such a massive star. Our final goal is
Emission from Pair-Instability Supernovae with Rotation
Pair-instability supernovae (PISNe) have been suggested as candidates for some superluminous supernovae, such as SN 2007bi, and as one of the dominant types of explosion occurring in the early
Pair-instability Supernovae in the Local Universe
The discovery of 150-300 M {sub ☉} stars in the Local Group and pair-instability supernova candidates at low redshifts has excited interest in this exotic explosion mechanism. Realistic light curves
Cosmological Impact of the Population III Hypernovae
We investigate the stellar feedback of Pop III hypernovae by using cosmology simulations with GADGET. Recent studies of the Pop III star formation suggested that these stars might be very massive and
Abundance anomalies in metal-poor stars from Population III supernova ejecta hydrodynamics
We present a simulation of the long-term evolution of a Population III supernova remnant in a cosmological minihalo. Employing passive Lagrangian tracer particles, we investigate how chemical
How the first stars regulated star formation. II. Enrichment by nearby supernovae
Metals from Population III (Pop III) supernovae led to the formation of less massive Pop II stars in the early universe, altering the course of evolution of primeval galaxies and cosmological
The supernova that destroyed a protogalaxy: prompt chemical enrichment and supermassive black hole growth
The first primitive galaxies formed from accretion and mergers by z ~ 15, and were primarily responsible for cosmological reionization and the chemical enrichment of the early cosmos. But a few of
Formation of massive black holes in rapidly growing pre-galactic gas clouds
A radiation hydrodynamics simulation of early galaxy formation suggests that the dynamics of structure formation, rather than the Lyman–Werner flux, drives the formation of massive black holes in the early Universe.
Finding the First Cosmic Explosions. IV. 90 - 140 M ☉ Pair-instability Supernovae
Population III stars that die as pair-instability supernovae are usually thought to fall in the mass range of 140 - 260 M⊙. However, several lines of work have now shown that rotation can build up


The Early Evolution of Primordial Pair-Instability Supernovae
The observational signatures of the first cosmic explosions and their chemical imprint on second-generation stars both crucially depend on how heavy elements mix within the star at the earliest
Pair‐instability supernovae at the epoch of reionization
Pristine stars with masses between ∼140 and 260 M⊙ are theoretically predicted to die as pair-instability supernovae. These very massive progenitors could come from Population III (Pop III) stars in
Massive stars that end their lives with helium cores in the range of 35-65 M ☉ are known to produce repeated thermonuclear outbursts due to a recurring pair-instability. In some of these events,
Supernova 2007bi as a pair-instability explosion
Observations of supernova SN 2007bi are reported, a luminous, slowly evolving object located within a dwarf galaxy, and it is shown that >3 of radioactive 56Ni was synthesized during the explosion and that the observations are well fitted by models of pair-instability supernovae.
The Formation of Population III Binaries from Cosmological Initial Conditions
A cosmological simulation in which the central 50 M⊙ clump breaks up into two cores having a mass ratio of two to one, with one fragment collapsing to densities of 10−8 grams per cubic centimeter is discussed.
Population III supernovae have been the focus of growing attention because of their potential to directly probe the properties of the first stars, particularly the most energetic events that can be
Understanding the properties of Population III (Pop III) stars is prerequisite to elucidating the nature of primeval galaxies, the chemical enrichment and reionization of the early intergalactic
One Hundred First Stars : Protostellar Evolution and the Final Masses
We perform a large set of radiation hydrodynamic simulations of primordial star formation in a fully cosmological context. Our statistical sample of 100 First Stars shows that the first generation of
Hydrogen-poor circumstellar shells from pulsational pair-instability supernovae with rapidly rotating progenitors
In certain mass ranges, massive stars can undergo a violent pulsation triggered by the electron/positron pair instability that ejects matter, but does not totally disrupt the star. After one or more
