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…
Tracing back a second-generation star stripped from Terzan 5 by the Galactic bar
Stefano O. Souza, Marica Valentini, Cristina Chiappini +6
The Galactic bulge hosts the Milky Way's oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge's primordial building blocks, making these stars witnesse…
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…
