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…
Energy equipartition in multiple-population globular clusters
A. R. Livernois, F. I. Aros, E. Vesperini +7
We present the results of Monte Carlo simulations aimed at exploring the evolution towards energy equipartition of first- (1G) and second-generation (2G) stars in multiple-populati…
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…
JWST imaging of the closest globular clusters -- IV. Chemistry, luminosity, and mass functions of the lowest-mass members in the NIRISS parallel fields
M. Libralato, R. Gerasimov, L. Bedin +9
We present observations of the two closest globular clusters, NGC 6121 and NGC 6397, taken with the NIRISS detector of JWST. The combination of our new JWST data with archival Hubb…
The HST Large Programme on Omega Centauri -- VII. The white dwarf cooling sequence
M. Scalco, M. Salaris, L. Bedin +9
We present a study of the white dwarf (WD) cooling sequence (CS) in the globular cluster (GC) Omega Centauri, the primary goal of a dedicated Hubble Space Telescope (HST) programme…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
