Probing the first generations of massive stars through fluorine in CEMP-no stars
Arthur Choplin, Georges Meynet
We investigate whether the first discovered fluorine-rich CEMP-no star, CS 29498043, can be explained by a very metal-poor rotating massive star. We consider single rotating ste…
Chemical evolution of close massive binaries -- tidally-enhanced or tidally-suppressed mixing?
Luca Sciarini, Sophie Rosu, Sylvia Ekström +3
One of the largest source of uncertainties in the predictions of stellar models comes from the internal transport mechanisms. In close massive binaries, previous theoretical studie…
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.…
pySTARBURST99: The Next Generation of STARBURST99
Calum Hawcroft, Claus Leitherer, Oskar Arangure +8
STARBURST99 is a population synthesis code tailored to predict the integrated properties or observational characteristics of star-forming galaxies. Here we present an update to STA…
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…
Strong nebular HeII emission induced by He ionizing photons escaping through the clumpy winds of massive stars
Arpita Roy, Mark R. Krumholz, Stefania Salvadori +8
The origin of nebular HeII-emission in both local and high-redshift galaxies remains an unsolved problem. Various theories have been proposed to explain it, including HeII-ionizati…
