Reconstructing the Milky Way chemical map with Galactic Chemical Evolution tool OMEGA+ from SDSS-MWM
Viola Hegedűs, Szabolcs Mészáros, Blanka Világos +4
We obtain two-infall galactic chemical evolution (GCE) models simulating the chemical evolution of the Milky Way as constrained by a golden sample of stellar abundances o…
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…
The chemical evolution of the solar neighbourhood for planet-hosting stars
Marco Pignatari, Thomas C. L. Trueman, Kate A. Womack +13
Theoretical physical-chemical models for the formation of planetary systems depend on data quality for the Sun's composition, that of stars in the solar neighbourhood, and of the e…
Chemical Evolution of Fluorine in the Milky Way
Kate A. Womack, Fiorenzo Vincenzo, Brad K. Gibson +5
Fluorine has many different potential sites and channels of production, making narrowing down a dominant site of fluorine production particularly challenging. In this work, we inve…
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…
Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution
T. C. L. Trueman, B. Côté, A. Yagüe López +5
Analysis of inclusions in primitive meteorites reveals that several short-lived radionuclides (SLRs) with half-lives Myr existed in the early Solar System (ESS). We inves…
The Fe(n, γ)Fe Cross Section from the Surrogate Ratio Method and Its Effect on the Fe Nucleosynthesis
S. Q. Yan, X. Y. Li, K. Nishio +39
The long-lived Fe (with a half-life of 2.62 Myr) is a crucial diagnostic of active nucleosynthesis in the Milky Way galaxy and in supernovae near the solar system. The neutr…
UVES analysis of red giants in the bulge globular cluster NGC 6522
B. Barbuy, E. Cantelli, L. Muniz +10
NGC 6522 is a moderately metal-poor bulge globular cluster ([Fe/H]1.0), and it is a well-studied representative among a number of moderately metal-poor blue horizontal bra…
The Impact of Nuclear Physics Uncertainties on Galactic Chemical Evolution Predictions
Benoit Côté, Pavel Denissenkov, Falk Herwig +7
Modeling the evolution of the elements in the Milky Way is a multidisciplinary and challenging task. In addition to simulating the 13 billion years evolution of our Galaxy, chemica…
Using failed supernovae to constrain the Galactic r-process element production
B. Wehmeyer, C. Frohlich, B. Côté +2
Rapid neutron capture process (r-process) elements have been detected in a large fraction of metal-poor halo stars, with abundances relative to iron (Fe) that vary by over two orde…
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…
Galactic Chemical Evolution of Radioactive Isotopes
Benoit Côté, Maria Lugaro, Rene Reifarth +4
The presence of short-lived (\,Myr) radioactive isotopes in meteoritic inclusions at the time of their formation represents a unique opportunity to study the circumstances th…
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…
JINA-NuGrid Galactic Chemical Evolution Pipeline
Benoit Côté, Christian Ritter, Falk Herwig +5
Galactic chemical evolution is a topic that involves nuclear physics, stellar evolution, galaxy evolution, observation, and cosmology. Continuous communication and feedback between…
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…
Uncertainties in Galactic Chemical Evolution Models
Benoit Côté, Christian Ritter, Brian W. O'Shea +4
We use a simple one-zone galactic chemical evolution model to quantify the uncertainties generated by the input parameters in numerical predictions, for a galaxy with properties si…
Galactic evolution of rapid neutron capture process abundances: the inhomogeneous approach
B. Wehmeyer, M. Pignatari, F. -K. Thielemann
For the origin of heavy r-process elements, different sources have been proposed, e.g., core-collapse supernovae or neutron star mergers. Old metal-poor stars carry the signature o…
