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 …
