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…
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…
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…
Enrichment of the Galactic disc with neutron capture elements: Sr
T. Mishenina, M. Pignatari, T. Gorbaneva +4
The enrichment history of heavy neutron-capture elements in the Milky Way disc provides fundamental information about the chemical evolution of our Galaxy and about the stellar sou…
Observing the metal-poor solar neighbourhood: a comparison of galactic chemical evolution predictions
T. Mishenina, M. Pignatari, B. Cot'e +14
Atmospheric parameters and chemical compositions for ten stars with metallicities in the region of -2.2< [Fe/H] <-0.6 were precisely determined using high resolution, high signal t…
Mn abundances in the stars of the Galactic disc with metallicities -1.0 < [Fe/H] < 0.3
T. Mishenina, T. Gorbaneva, M. Pignatari +2
In this work we present and discuss the observations of the Mn abundances for 247 FGK dwarfs, located in the Galactic disc with metallicity -1<Fe/H]<+0.3. The observed stars belong…
Abundances of neutron-capture elements in stars of the galactic disk substructures
T. V. Mishenina, M. Pignatari, S. A. Korotin +5
The aim of this work is to present and discuss the observations of the iron peak (Fe, Ni) and neutron-capture element (Y, Zr, Ba, La, Ce, Nd, Sm, and Eu) abundances for 276 FGK dwa…
The NLTE Barium Abundance in Dwarf Stars in the Metallicity Range of -1 < [Fe/H] < +0.3
S. Korotin, T. Mishenina, T. Gorbaneva +1
We present the results of determination of the barium abundance considering the non-LTE (NLTE) effects in 172 dwarf stars in the metallicity range of -1< [Fe/H] <+0.3, assigned to…
Elemental abundances in the atmosphere of clump giants
T. V. Mishenina, O. Bienaym'e, T. I. Gorbaneva +4
The aim of this paper is to provide the fundamental parameters and abundances for a large sample of local clump giants with a high accuracy. The selection of clump stars for the sa…
