| description | Despite significant progress in the understanding of <i>galactic nucleosynthesis</i> and its influence on the solar system neighborhood, challenges remain in the understanding of enrichment of the <i>solar system</i> 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 <i>A</i> to higher <i>A</i>) but nuclear-<i>fission</i> (from higher <i>A</i> to lower <i>A</i>)—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. |
