Radial abundance gradients of 18 elements in Galactic open clusters from infrared MWM spectra A detailed analysis of 655 giants in 133 clusters
S. Bijavara Seshashayana, H. Jönsson, V. D'Orazi +3
Open clusters are powerful tools for studying the Milky Way. While large spectroscopic surveys now provide spectra for many cluster members, automated pipelines and heterogeneous m…
Stellar Population Astrophysics (SPA) with the TNG. Beyond the iron peak: Galactic evolution of molybdenum, ruthenium and zirconium through open clusters
Natalia Alvarez-Baena, Valentina D'Orazi, Christopher Sneden +11
The paper measures molybdenum, ruthenium, and zirconium abundances in 81 stars from 30 open clusters using high‑resolution HARPS‑N spectra to investigate the Galactic chemical evol…
The open cluster NGC 2509. Stellar rotation and main sequence turnoff extension from FLAMES spectroscopy
C. Boeche, J. Alonso-Santiago, A. Bragaglia +8
NGC 2509 is a distant (~2.5 kpc) and little-studied open cluster located in the third Galactic quadrant. It is a moderately old cluster, whose age has not yet been precisely determ…
Observational Signatures and Constraints on the Intermediate Neutron-Capture Process. The Case of the CEMP star TYC 6044-714-1 (RAVE J094921.8-161722)
Riano E. Giribaldi, Diego Vescovi, Laura Magrini +6
Observational abundances of CEMP stars with patterns in between those produced by the rapid and slow nucleosynthesis processes (CEMP-rs stars) are currently invoked as evidence of…
Stellar Population Astrophysics (SPA) with the TNG. CNO abundances in 28 open clusters
Bruno ÄurjuriÄ, Arnas Drazdauskas, Gražina TautvaiÅ¡ienÄ +4
Aims. Our main aim with this work was to enlarge the pool of open clusters with determined carbon, nitrogen, and oxygen abundances in evolved giants to further advance chemical clo…
No country for old stars -Spectroscopic confirmation of the first intermediate-age RR Lyrae in the open cluster Trumpler 5
Valentina D'Orazi, Cecilia Mateu, Giuliano Iorio +13
RR Lyrae stars are widely considered tracers of ancient (greater than 10 Gyr), metal-poor stellar populations. However, recent kinematic and photometric studies suggest the existen…
