oMEGACat. V. Helium Enrichment in ω Centauri as a Function of Metallicity

Constraining the helium enhancement in stars is critical for understanding the formation mechanisms of multiple populations in star clusters. However, measuring helium variations for many stars within a cluster remains observationally challenging. We use Hubble Space Telescope photometry combined wi...
