What changed

Combined relativistic electron degeneracy with a polytropic stellar model to obtain an upper mass for an ideal white dwarf.

Scientific scope

Combined relativistic electron degeneracy with a polytropic stellar model to obtain an upper mass for an ideal white dwarf. Scope limitation: The two-page paper gives approximately 0.91 solar masses under its stated composition assumption, including a molecular weight of 2.5. Substituting the later familiar numerical value would misrepresent this source. The result concerns the idealized model and compares earlier Stoner estimates; it does not establish the fate of every massive star. The cited original text supports this scoped reading; a local source copy is not distributed. No calculation was replayed.
