We present stellar evolution calculations for Population III stars for both single- and binary- star evolutions. Our models include 10- and 16.5-Msingle stars and a 10-Mmodel star that undergoes an episode of accretion resulting in a final mass of 16.1 M� . For comparison, we present the evolution of a solar heavy element abundance model. We use the structure from late-stage evolution models to calculate simulated supernova light curves. Light curve comparisons are made between accretion and… 
The First Billion Years project: the impact of stellar radiation on the co-evolution of Populations II and III
With the first metal enrichment by Population (Pop) III supernovae (SNe), the formation of the first metal-enriched, Pop II stars becomes possible. In turn, Pop III star formation and early metal
The impact of a supernova explosion in a very massive binary
We consider the effect of a supernova (SN) explosion in a very massive binary that is expected to form in a portion of Population III stars with the mass higher than 100 M ⊙ . In a Population III
The effects of convection criteria on the evolution of Population III stars and the detectability of their supernovae
The first stars continue to elude modern telescopes, but much has been accomplished in observing the glow of the first galaxies. As detection capabilities improve we will eventually
Formation of the First Galaxies: Theory and Simulations
The properties of the first galaxies are shaped in large part by the first generations of stars, which emit high energy radiation and unleash both large amounts of mechanical energy and the first
QUARK-NOVAE, COSMIC REIONIZATION, AND EARLY r-PROCESS ELEMENT PRODUCTION
We examine the case for quark-novae (QNe) as possible sources for the reionization and early metal enrichment of the universe. QNe are predicted to arise from the explosive collapse (and conversion)
The numerical frontier of the high-redshift Universe
The first stars are believed to have formed a few hundred million years after the big bang in so-called dark matter minihalos with masses ∼106 M⊙$\sim 10^{6}\mbox{ M}_{\odot}$. Their radiation lit up
Galaxy formation theory
We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of
The extremely low metallicity star SDSS J102915+172927: a subgiant scenario
Spectroscopic analysis of the Galactic halo star SDSS J102915+172927 has shown it to have a very low heavy element abundance, Z < 7.4×10 -7 , with [Fe/H] = –4.89 ± 0.10 and an upper limit on the C
STRUCTURAL EFFECTS OF MAGNETIC FIELDS IN BROWN DWARFS
In the brown dwarf (BD) binary 2M0535 - 05, Stassun et al. have reported that the more massive primary has a lower T{sub eff} than the less massive secondary. Here, we report results obtained by an
Computational Investigation of Stellar Cooling, Noble Gas Nucleation, and Organic Molecular Spectra
Since the advent and optimization of the Hartree-Fock method, quantum chemistry has been utilized to investigate systems operating on timeframes and environments traditionally unavailable to
