AWhat changed
Related thermal ionization to temperature, pressure and ionization potential and used the relation to explain stellar and solar spectral behavior.
Scientific scope
The record is the exact 1920 Philosophical Magazine paper. Saha’s shorter Nature letter, related papers in the series, later stellar-abundance inference and subsequent refinements remain separate.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1920 Philosophical Magazine paper. Saha’s shorter Nature letter, related papers in the series, later stellar-abundance inference and subsequent refinements remain separate.
