Hypothesis about Enrichment of Solar System
Despite significant progress in the understanding of galactic nucleosynthesis
and its influence on the solar system neighborhood, challenges remain in the
understanding of enrichment of the solar system itself. Based on the detailed
review of multi-disciplinary literature, we propose a scenario that an event of
nucleogenesis -- not nucleosynthesis (from lower nucleon numbers A to higher A)
but nuclear-fission (from higher A to lower A) -- occurred in the inner part of
the solar system at one of the stages of its evolution. We propose a feasible
mechanism of implementation of such event. The occurrence of such event could
help explain the puzzles in yet-unresolved isotopic abundances, certain
meteoritic anomalies, as well as peculiarities in the solar system's
composition and planetary structure. We also discuss experimental data and
available results from existing models (in several relevant sub-fields) that
provide support and/or appear consistent with the hypothesis.Comment: 73 pages, 31 figures. arXiv admin note: text overlap with
