Stellar Population Astrophysics (SPA) with the TNG 23 IR elemental abundances of 114 giant stars in 41 Open Clusters
Shilpa Bijavara Seshashayana, Henrik Jönsson, Valentina D'Orazi +4
Open clusters have been extensively used as tracers of Galactic chemical evolution, as their constituent stars possess shared characteristics, including age, Galactocentric radius,…

Stellar population astrophysics (SPA) with the TNG. The Phosphorus abundance on the young side of MilkyWay
Mingjie Jian, Xiaoting Fu, Valentina D'Orazi +11
We present phosphorus abundance measurements for a total of 102 giant stars, including 82 stars in 24 open clusters and 20 Cepheids, based on high-resolution near-infrared spectra…

Optical spectroscopic signatures of the red giant evolutionary state
Ella Xi Wang, Melissa Ness, Thomas Nordlander +17
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…
