New Paper: Antoniadis et al. 2025: Investigating the metallicity dependence of the mass-loss rate relation of red supergiants

Kostas has been actively working on determining the mass loss rate for Red Supergiants across various metallicities. We had plenty of these sources for NGC 6822 so it was natural to include them in a straight comparison with SMC, LMC and the Milky Way. However, each of these galaxies have …

New paper: Zapartas et al. 2024: The effect of mass loss in models of red supergiants in the Small Magellanic Cloud:

During the ASSESS project we carried out tons of observations and careful analysis in order to identify mass-losing evolved stars. At the same time though, Manos Zapartas was taking advantage of the new red supergiant mass loss fits we managed and put them into some perspective with theory. Equipped with …
