The dramatic transition of the extreme Red Supergiant WOH G64 to a Yellow Hypergiant
G. Munoz-Sanchez, M. Kalitsounaki, S. de Wit +8
Red Supergiants (RSGs) are cool, evolved massive stars in their final evolutionary stage before exploding as a supernova. However, the evolution and fate of the most luminous RSGs…

Investigating the metallicity dependence of the mass-loss rate relation of red supergiants
K. Antoniadis, E. Zapartas, A. Z. Bonanos +8
Red supergiants (RSGs) are cool and evolved massive stars exhibiting enhanced mass loss compared to their main sequence phase, affecting their evolution and fate. However, the theo…

A new long gamma-ray burst formation pathway at solar metallicity
M. M. Briel, T. Fragos, O. S. Salafia +11
Context. Long gamma-ray bursts (LGRBs) are generally observed in low-metallicity environments. However, 10 to 20 per cent of LGRBs at redshift are associated with near-solar…
