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
Context: Open clusters serve as key laboratories for studying the chemical evolution of the Milky Way. In particular, leveraging these coeval groups of stars to study elements beyo…
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…
Peculiarities of the chemical enrichment of metal-poor Stars in the Milky Way Galaxy
T. Mishenina, M. Pignatari, I. Usenko +5
The oldest stars in the Milky Way are metal-poor with [Fe/H] < -- 1.0, displaying peculiar elemental abundances compared to solar values. The relative variations in the chemical co…
Enrichment of the Galactic disc with neutron-capture elements: Gd, Dy, and Th
T. Mishenina, M. Pignatari, T. Gorbaneva +4
The study of the origin of heavy elements is one of the main goals of nuclear astrophysics. In this paper, we present new observational data for the heavy -process elements gado…
Chemical composition of stars with massive planets
T. Mishenina, N. Basak, V. Adibekyan +2
Stellar parameters of 25 planet-hosting stars and abundances of Li, C, O, Na, Mg, Al, S, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Zn, Y, Zr, Ba, Ce, Pr, Nd, Sm and Eu, were studied based…
Enrichment of the Galactic disc with neutron-capture elements: Mo and Ru
Tamara Mishenina, Marco Pignatari, Tatiana Gorbaneva +4
We present new observational data for the heavy elements molybdenum (Mo, Z = 42) and ruthenium (Ru, Z = 44) in F-, G-, and K-stars belonging to different substructures of the Milky…
