Аннотация
The OLIMPIYA project studies tracks of heavy nuclei from Galactic cosmic rays (GCR) in olivine crystals from two meteorites-pallasites of different cosmic-ray exposure ages. The updated data presented is used to analyze the history of local variations in the GCR flux over the past ∼200 Myr. The analysis demonstrates the difference in the abundances of heavy nuclei registered in the meteorites and satellite detectors, as well as in the meteorites themselves. This difference may indicate the influence of at least two rare cosmic sources of r-element nucleosynthesis on GCR fluxes in the vicinity of the Solar System. Two possible sources, namely Supernovae (SN) and asymptotic giant branch stars (AGB) events versus the neutron star mergers or neutron star - black hole mergers (NSM) events, are compared in terms of the yield of r-elements. © 2022 COSPAR
