Apsidal Motion in O-Star Binaries: GENEC rotating binary models put to the k2-test
Sophie Rosu, Luca Sciarini, Sylvia Ekström +1
Unveiling massive stars' internal structure and the physical origin and efficiency of the internal mixing processes? It is now possible using the apsidal motion rate in close eccen…

The impact of wind mass loss on nucleosynthesis and yields of very massive stars at low metallicity
Erin R. Higgins, Jorick S. Vink, Raphael Hirschi +2
The chemical feedback from stellar winds in low metallicity (Z) environments is key for understanding the evolution of globular clusters and the early Universe. With disproportiona…

Evolving massive stars to core collapse with GENEC: Extension of equation of state, opacities and effective nuclear network
Adam Griffiths, Miguel-Ã Aloy, Raphael Hirschi +6
Stars with initial mass above roughly 8 solar masses will evolve to form a core made of iron group elements at which point no further exothermic nuclear reactions between charged n…
