Effects of chemically homogeneous evolution of the first stars on the 21-cm signal and reionization
Boyuan Liu, Daniel Kessler, Thomas Gessey-Jones +6
The first generation of stars, known as Population III (Pop III), played a crucial role in the early Universe through their unique formation environment and metal-free composition.…
Signatures of Rapidly Rotating Stars with Chemically Homogeneous Evolution in the First Galaxies
Boyuan Liu, Yves Sibony, Georges Meynet +1
The James Webb Space Telescope (JWST) has revealed an unexpectedly high abundance of UV luminous galaxies at redshifts , challenging `standard' galaxy formation models…
Fast-rotating massive Population~III stars as possible sources of extreme N-enrichment in high-redshift galaxies
Devesh Nandal, Yves Sibony, Sophie Tsiatsiou
We present an analysis of the chemical compositions in high-redshift galaxies, with a focus on the nitrogen-enhanced galaxies GN-z11 and CEERS-1019. We use stellar models of massiv…
Stellar winds and metal enrichment from fast-rotating Population III stars
Boyuan Liu, Yves Sibony, Georges Meynet +1
Stellar winds from fast-rotating Population III (Pop III) stars have long been suspected to make important contributions to early metal enrichment, as features in the nucleosynthes…
