Stellar Yields of Rapidly Rotating Population III Stars for the High Redshift Universe
Devesh Nandal, Konstantinos Topalakis, Vasilisa Sergienko +6
JWST has revealed rapid nitrogen enrichment in high redshift galaxies, renewing the need for stellar yields that follow metal free stars beyond the main sequence and across their f…
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…
Chemical Evolution of R-process Elements in Stars (CERES) II. The impact of stellar evolution and rotation on light and heavy elements
Raphaela Fernandes de Melo, Linda Lombardo, Arthur Alencastro Puls +4
Context. Carbon, nitrogen, and oxygen are the most abundant elements throughout the universe, after hydrogen and helium. Studying these elements in low-metallicity stars can provid…
Grids of stellar models with rotation VIII: Models from 1.7 to 500 at metallicity
Yves Sibony, Kendall G. Shepherd, Norhasliza Yusof +12
Grids of stellar evolution models with rotation using the Geneva stellar evolution code (Genec) have been published for a wide range of metallicities. We introduce the last remaini…
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…
Rapidly rotating Population III stellar models as a source of primary nitrogen
Sophie Tsiatsiou, Yves Sibony, Devesh Nandal +12
The first stars might have been fast rotators. This would have important consequences for their radiative, mechanical and chemical feedback. We discuss the impact of fast initial r…
