Titolo: | Neutron-capture measurement candidates for the r-process in neutron star mergers | Autori: | VESCOVI, DIEGO Reifarth, René CRISTALLO, Sergio Couture, Aaron |
Data pubblicazione: | 2022 | Rivista: | FRONTIERS IN ASTRONOMY AND SPACE SCIENCES | Numero: | 9 | Abstract: | Neutron star mergers (NSMs) are one of the astrophysical sites for the occurrence of the rapid neutron capture process (r-process). After a merger, the ejected neutron-rich matter hosts the production of radioactive heavy nuclei located far from the stability valley. Their nuclear physics properties are key inputs for r-process nucleosynthesis calculations. Here, we focus on the importance of neutron-capture rates and perform a sensitivity study for typical outflows from NSMs. We identify the rates with the highest impact on the final r-process abundance pattern and the nuclear energy release, therefore determining the nucleosynthesis in NSMs. A list of major n-capture rates affecting individual isotopes and elements production is also provided. | URI: | http://hdl.handle.net/20.500.12386/32968 | URL: | https://api.elsevier.com/content/abstract/scopus_id/85140319482 https://www.frontiersin.org/articles/10.3389/fspas.2022.994980/full |
