r-process observations [PDF]

open access: yesEPJ Web of Conferences, 2018
The r-process nucleosynthesis in the Universe is constrained by observations of chemical abundances of the Solar System and those of old stars that should record the products of the r-process events in the early Universe. This review provides a brief overview of the observational technique to determine chemical abundances of stars.

Current Status of r-Process Nucleosynthesis

open access: yes, 2019
The rapid neutron capture process (r process) is believed to be responsible for about half of the production of the elements heavier than iron and contributes to abundances of some lighter nuclides as well. A universal pattern of r-process element abundances is observed in some metal-poor stars of the Galactic halo.

Illustrations of serial mediation using PROCESS, Mplus and R [PDF]

open access: yes, 2022
There has been an increased interest among researchers in the behavourial and social sciences for mediation models. This interest is well deserved: mediation can explain via intermediate variables the relationship between an independent variable and a ...

r-Process elements from magnetorotational hypernovae [PDF]

open access: yesNature, 2021
Neutron-star mergers were recently confirmed as sites of rapid-neutron-capture (r-process) nucleosynthesis. However, in Galactic chemical evolution models, neutron-star mergers alone cannot reproduce the observed element abundance patterns of extremely metal-poor stars, which indicates the existence of other sites of r-process nucleosynthesis.

Neutron star mergers and rare core-collapse supernovae as sources of r-process enrichment in simulated galaxies [PDF]

open access: yes, 2020
We use cosmological, magnetohydrodynamical simulations of Milky Way-mass galaxies from the Auriga project to study their enrichment with rapid neutron capture (r-process) elements. We implement a variety of enrichment models from both binary neutron star
