Multiple populations along the asymptotic giant branch: a Gaia+APOGEE study of 22 Galactic globular clusters
Emanuele Dondoglio, A. P. Milone, A. F. Marino +9
We present an investigation of multiple stellar populations along the asymptotic giant branch (AGB) in 22 globular clusters (GCs), exploiting APOGEE spectroscopy combined with AGB…

Semi-empirical versus Theoretical Stellar Population Models: a comparison with Star Clusters
Randa Asad, Paula R. T. Coelho, Johina M. John +3
Stellar population synthesis (SPS) models are a key tool for deriving the age, metallicity, radial velocity and reddening of star clusters from their integrated spectra. Using a sa…

NGC1856: Using machine learning techniques to uncover detailed stellar abundances from MUSE data
Randa Asa'd, S. Hernandez, Johina M. John +5
We present the first application of the novel approach based on data-driven machine learning methods applied to Multi-Unit Spectroscopic Explorer (MUSE) field data to derive stella…
