s-process framework: σ·N = const along s-only path (slow neutron capture local equilibrium)

Layer 2 — Chemistryin the cosmochemistry subtree

The s-process local-equilibrium framework — a foundational result in stellar nucleosynthesis (Burbidge, Burbidge, Fowler & Hoyle 1957, 'B²FH'; Cameron 1957) that reduces the nucleo-synthetic network for slow-neutron-capture isotopes to a…
