oMEGACat V: Helium Enrichment in Centauri as a Function of Metallicity

C. Clontz, A. C. Seth, Z. Wang +12

Constraining the helium enhancement in stars is critical for understanding the formation mechanisms of multiple populations in star clusters. However, measuring helium variations f…

oMEGACat IV: Constraining Ages of Omega Centauri sub-giant branch stars with HST and MUSE

C. Clontz, A. C. Seth, A. Dotter +13

We present age estimates for over 8100 sub-giant branch (SGB) stars in Omega Centauri ( Cen) to study its star formation history. Our large data set, which combines multi-wavele…

oMEGACat II -- Photometry and proper motions for 1.4 million stars in Omega Centauri and its rotation in the plane of the sky

Maximilian Häberle, Nadine Neumayer, Andrea Bellini +15

Omega Centauri ( Cen) is the most massive globular cluster of the Milky Way. It is thought to be the nucleus of an accreted dwarf galaxy because of its high mass and its complex…
