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 ...

A needle in a haystack? Catching Population III stars in the epoch of reionization: I. Population III star-forming environments

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.

Survival of Population III stars

Proceedings of the International Astronomical Union, 2018
AbstractIn our earlier studyDutta (2016a), it has been shown that a number of primordial protostars (the ‘first stars’ in the Universe, also known as Population III or Pop III stars) are being ejected from the cluster of their origin with the velocity exceeding their escape velocity.

F19(p,γ)20Ne and F19(p,α)O16 reaction rates and their effect on calcium production in Population III stars from hot CNO breakout

, 2021
First generation, or Population III, stars have a different evolution than those of later generations owing to their initial primordial abundance composition. Most notably, the lack of carbon, oxygen, and nitrogen means that primordial massive stars must

Nucleosynthesis in Aspherical Explosions of Population III Stars

AIP Conference Proceedings, 2008
We present the nucleosynthetic yields of Population III core‐collapse supernovae (SNe) focusing on the cases of hyper‐energetic (Hypernovae, HNe) and hyper‐aspherical (jet‐induced) explosions. We show that (1) the explosions with large energy deposition rate, Ėdep, are observed as GRB‐HNe and their yields can explain the abundances of normal extremely ...
