31 Oct 2019 | | Abstract: | 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, chemical evolution simulations must keep
track of the elements synthesized and ejected from every astrophysical site of
interest (e.g., supernova, compact binary merger). The elemental abundances of
such ejecta, which are a fundamental input for chemical evolution codes, are
usually taken from theoretical nucleosynthesis calculations performed by the
nuclear astrophysics community. Therefore, almost all chemical evolution
predictions rely on the nuclear physics behind those calculations. In this
proceedings, we highlight the impact of nuclear physics uncertainties on
galactic chemical evolution predictions. We demonstrate that nuclear physics
and galactic evolution uncertainties both have a significant impact on
interpreting the origin of neutron-capture elements in our Solar System. Those
results serve as a motivation to create and maintain collaborations between the
fields of nuclear astrophysics and galaxy evolution. | | Source: | arXiv, 1911.0035 | | Services: | Forum | Review | PDF | Favorites | |
