Modelling population III stars for seminumerical simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Theoretically modelling the 21-cm signals caused by Population III stars (Pop III stars) is the key to extracting fruitful information on Pop III stars from current and forthcoming 21-cm observations. In this work, we develop a new module of Pop III stars in which the escape fractions of ionizing photons and Lyman–Werner (LW ...

Evolution of Massive Population III Stars
Acta Polytechnica CTU Proceedings, 2014 While the evolution of massive stars in the local Universe is dominated by mass-loss, the evolution of massive Population III stars should be dominated by rotation.

The most massive Population III stars
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Recent data from the JWST suggest that there are realistic prospects for detecting the earliest generation of stars at redshift ∼20. These metal-poor, gaseous Population III (Pop III) stars are likely in the mass range $10\!-\!10^3\, {\rm M}_{\odot }$ .

Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Despite extensive search efforts, direct observations of the first [Population III (Pop III)] stars have not yet succeeded. Theoretical studies have suggested that late Pop III star formation is still possible in pristine clouds of high-mass galaxies, co-existing with Pop II stars, down to the epoch of reionization.

Extremely Metal-Poor Asymptotic Giant Branch Stars
Universe, 2022 Little is known about the first stars, but hints on this stellar population can be derived from the peculiar chemical composition of the most metal-poor objects in the Milky Way and in resolved stellar populations of nearby galaxies.

The search for Population III stars [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractPopulation III stars, the first generation of stars formed from primordial Big Bang material with a top–heavy IMF, should contribute substantially to the Universe reionization and they are crucial for understanding the early metal enrichment of galaxies.

The evolution of supermassive Population III stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Supermassive primordial stars forming in atomically-cooled halos at $z \sim15-20$ are currently thought to be the progenitors of the earliest quasars in the Universe. In this picture, the star evolves under accretion rates of $0.1 - 1$ $M_\odot$ yr$^{-1}$ until the general relativistic instability triggers its collapse to a black hole at masses of ...

Merger Conditions of Population III Protostar Binaries
The Astrophysical Journal, 2023 Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries in the protostellar accretion stage is key to understanding their formation
