LAP1-B: First Observational Candidate for a Population III Star Cluster and Its Implications for Thermosynthesis Cosmological Theory

We present a rigorous theoretical and observational analysis of LAP1-B, a gravitationally lensed stellar cluster at redshift z = 6.61 ± 0.02, corresponding to a cosmic age of 830 ± 15 Myr, recently observed by the James Webb Space Telescope (JWST). Spectroscopic data reveal extreme properties: an Hα equivalent width of 4200 Å, absence of metal lines (e.g., [O III] < 180 Å), and a top-heavy initial mass function (IMF), consistent with Population III (Pop III) star formation. Within the framework of Thermosynthesis Cosmological Theory (TTC), we interpret LAP1-B as a natural outcome of early thermosynthetic cycles, where rapid feedback from pair-instability supernovae (PISNe) drives chemical enrichment on sub-Myr timescales. We demonstrate quantitative agreement between observations and TTC predictions for primordial halos, including IMF shape, star formationrate, and metal yields. The system provides direct empirical support for TTC’s resolution of the early structure formation tension and validates its core tenet: accelerated chemical enrichment via recursive, entropy-driven stellar nucleosynthesis.
