Growing evidence suggests that the first generation of stars may have been quite massive (~100-300 M☉). Could these stars have left a distinct nucleosynthetic signature? We explore the nucleosynthesis of helium cores in the mass range MHe = 64-133 M☉, corresponding to main-sequence star masses of approximately 140-260 M☉. Above MHe = 133 M☉, without rotation and using current reaction rates, a black hole is formed, and no nucleosynthesis is ejected. For lighter helium core masses, ~40-63 M… 
The evolution and explosion of metal-free stars with masses 10–100 M☉ are followed, and their nucleosynthetic yields, light curves, and remnant masses determined. Such stars would have been the first
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
Nebular spectra of pair-instability supernovae
If very massive stars (M >~ 100 Msun) can form and avoid too strong mass loss during their evolution, they are predicted to explode as pair-instability supernovae (PISNe). One critical test for
Explosion and nucleosynthesis of low redshift pair instability supernovae
Both recent observations and stellar evolution models suggest that pair-instability supernovae (PISNe) could occur in the local Universe, at metallicities below Z_Sun/3. Previous PISN models were
Preserving chemical signatures of primordial star formation in the first low-mass stars
We model early star forming regions and their chemical enrichment by Population III (Pop III) supernovae with nucleosynthetic yields featuring high [C/Fe] ratios and pair-instability supernova (PISN)
Nucleosynthesis in Black-Hole-Forming Supernovae
Stars more massive than ∼ 20 − 25 M⨀ form a black hole at the end of their evolution. Stars with non-rotating black holes are likely to collapse “quietly” ejecting a small amount of heavy elements
Recent studies suggest that metal-poor stars enhanced in carbon but containing low levels of neutron-capture elements may have been among the first to incorporate the nucleosynthesis products of the
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.
Nucleosynthesis, Reionization, and the Mass Function of the First Stars
We critique the hypothesis that the first stars were very massive stars (VMSs; M > 140 M☉). We review the two major lines of evidence for the existence of VMSs: (1) that the relative metal abundances


Pair‐Instability Supernovae, Gravity Waves, and Gamma‐Ray Transients
Growing evidence suggests that the first generation of stars may have been quite massive (~100-300 M☉). If they retain their high mass until death, such stars will, after about 3 Myr, make
Evolution and Nucleosynthesis of Metal-Free Massive Stars
We calculate presupernova evolutions and supernova explosions of massive stars (M=13-25 Mo) for various metallicities. We find the following characteristic abundance patterns of nucleosynthesis in
Nucleosynthesis in massive stars with improved nuclear and stellar physics
We present the first calculations to follow the evolution of all stable nuclei and their radioactive progenitors in stellar models computed from the onset of central hydrogen burning through
Forming the First Stars in the Universe: The Fragmentation of Primordial Gas.
This work investigates the fragmentation properties of metal-free gas in the context of a hierarchical model of structure formation and finds that the gas dissipatively settles into a rotationally supported disk that has a very filamentary morphology.
Reheating of the Universe and Population III
We note that current observational evidence strongly favors a conventional recombination of ionized matter subsequent to redshift z = 1200, followed by reionization prior to redshift z = 5 and
Mass Limits For Black Hole Formation
We present a series of two-dimensional core-collapse supernova simulations for a range of progenitor masses and different input physics. These models predict a range of supernova energies and compact
On the Stability of Very Massive Primordial Stars
The stability of metal-free very massive stars (Z = 0; M = 120-500 M☉) is analyzed and compared with metal-enriched stars. Such zero-metallicity stars are unstable to nuclear-powered radial
Theoretical Models for Supernovae
The results of recent numerical simulations of supernova explosions are presented and a variety of topics discussed. Particular emphasis is given to i) the nucleosynthesis expected from intermediate
Nucleosynthesis in Type II supernovae and the abundances in metal-poor stars
We explore the effects on nucleosynthesis in Type II supernovae of various parameters (mass cut, neutron excess, explosion energy, progenitor mass) in order to explain the observed trends of the
