It has been proposed theoretically that the first generation of stars in the Universe (population III) would be as massive as 100 solar masses (100 M[circdot]), because of inefficient cooling of the precursor gas clouds. Recently, the most iron-deficient (but still carbon-rich) low-mass star—HE0107–5240—was discovered. If this is a population III star that gained its metals (elements heavier than helium) after its formation, it would challenge the theoretical picture of the formation of the… 
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
Relics of Metal-free Low-Mass Stars Exploding as Thermonuclear Supernovae
Renewed interest in the first stars that were formed in the universe has led to the discovery of extremely iron-poor stars. Since several competing scenarios exist, our understanding of the mass
Faint Population III supernovae as the origin of the most iron-poor stars
The most iron-poor stars in the Milky Way provide important observational clues to the astrophysical objects that enriched the primordial gas with heavy elements. Among them, the recently discovered
Low-energy Population III supernovae and the origin of extremely metal-poor stars
Some ancient, dim, metal-poor stars may have formed in the ashes of the first supernovae (SNe). If their chemical abundances can be reconciled with the elemental yields of specific Population III
Primordial Stellar Feedback and the Origin of Hyper-Metal-poor Stars
The apparent absence of stars in the Milky Way halo with -5 ≲ [Fe/H] ≲ -4 suggests that the gas out of which the halo stars were born experienced a period of low or delayed star formation after the
NUCLEOSYNTHESIS AND EVOLUTION OF MASSIVE METAL-FREE STARS
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
CARBON-ENHANCED METAL-POOR STARS: RELICS FROM THE DARK AGES
We use detailed nucleosynthesis calculations and a realistic prescription for the environment of the first stars to explore the first episodes of chemical enrichment that occurred during the dark
Carbon-rich extremely metal poor stars: signatures of Population III asymptotic giant branch stars in binary systems
We use the Cambridge stellar evolution code STARS to model the evolution and nucleosynthesis of zero-metallicity intermediate-mass stars. We investigate the effect of duplicity on the nucleosynthesis
Carbon-enhanced hyper-metal-poor stars and the stellar IMF at low metallicity
The two known "hyper-metal-poor" (HMP) stars, HE 0107-5240 and HE 1327-2326, have extremely high enhancements of the light elements C, N, and O relative to Fe and appear to represent a statistically
Supernova Nucleosynthesis in Population III 13-50 M☉ Stars and Abundance Patterns of Extremely Metal-poor Stars
We perform hydrodynamic and nucleosynthesis calculations of core-collapse supernovae (SNe) and hypernovae (HNe) of Population (Pop) III stars. We provide new yields for the main-sequence mass of MMS

First Stars, Very Massive Black Holes, and Metals
Recent studies suggest that the initial mass function (IMF) of the first stars (Population III) is likely to have been extremely top-heavy, unlike what is observed at present. We propose a scenario

A stellar relic from the early Milky Way
TLDR
This work reports the discovery of a low-mass star with an iron abundance as low as 1/200,000 of the solar value, which suggests that population III stars could still exist and that the first generation of stars also contained long-livedLow-mass objects.

The Origin of Extremely Metal-poor Carbon Stars and the Search for Population III
TLDR
It is shown that low-mass, extremely metal-poor stars evolve into carbon stars along paths that are quite different from those followed by more metal-rich stars of younger populations, allowing us, in principle, to distinguish the brightest survivors of the first generations of stars formed in the universe (Population III carbon stars) from stars belonging to younger populations.
Nucleosynthesis and Clump Formation in a Core-Collapse Supernova.
TLDR
It is found that newly formed iron-group elements are distributed throughout the inner half of the helium core by Rayleigh-Taylor instabilities at the (Ni + Si)/O and (C + O)/He interfaces, seeded by convective overturn during the early stages of the explosion.

It is concluded that at most one massive metal-free star forms per pregalactic halo, consistent with recent abundance measurements of metal-poor galactic halo stars.
