The fate of rotating massive stars across cosmic times
R. Hirschi, K. Goodman, G. Meynet +9
The initial mass and metallicity of stars both have a strong impact on their fate. Stellar axial rotation also has a strong impact on the structure and evolution of massive stars.…
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.…
Fluorine production in He-burning regions of massive stars during cosmic history
Sophie Tsiatsiou, Georges Meynet, Eoin Farrell +11
The origin of fluorine is still a debated question. AGB stars synthesise this element and likely contribute significantly to its synthesis in the present-day Universe. However, it…
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…
