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…

Molybdenum and ruthenium in the Galactic disk: A closer look at their nucleosynthesis components
Tamara Mishenina, Teresa Kurtukian-Nieto, Tatiana Gorbaneva +3
The stellar origin of the elements molybdenum (Mo, Z=42) and ruthenium (Ru, Z=44) is still a matter of debate. Studying their abundances provides valuable insights into nucleosynth…
