Hypothesis about Enrichment of Solar System

TL;DR

This paper hypothesizes that a nuclear fission event in the early solar system could explain isotopic anomalies and meteoritic irregularities, supported by literature review and existing models.

Contribution

It introduces a novel hypothesis of nuclear fission in the solar system's history and proposes a feasible mechanism for this event.

Findings

Supports hypothesis with existing experimental data

Aligns with observed isotopic anomalies

Provides a plausible mechanism for nuclear fission event

Abstract

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.
