Element abundances of galactic RGB stars in the APO-K2 catalogue. Dissimilarity in the scaling with [/Fe]
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
We conducted an investigation on the chemical abundances of 4,316 stars in the red giant branch (RGB) phase from the recently released APO-K2 catalogue. Our aim was to characterize…
Robust statistical tools for identifying multiple stellar populations in globular clusters in the presence of measurement errors. A case study: NGC 2808
G. Valle, M. Dell'Omodarme, E. Tognelli
The finding of multiple stellar populations (MP), defined by patterns in the stellar element abundances, is nowadays considered a distinctive feature of globular clusters. However,…
Bayesian calibration of the mixing length parameter and of the helium-to-metal enrichment ratio with open clusters: the Hyades test-bed
E. Tognelli, M. Dell'Omodarme, G. Valle +2
We tested the capability of a Bayesian procedure to calibrate both the helium abundance and the mixing length parameter (), using precise photometric data for main-sequence…
