The Vogt–Russell theorem states that the structure of a star, in hydrostatic and thermal equilibrium with all energy derived from nuclear reactions, is uniquely determined by its mass and the distribution of chemical elements throughout its interior. Although referred to as a theorem, the Vogt–Russell theorem has never been formally proved. The theorem is named after astronomers Heinrich Vogt and Henry Norris Russell, who devised it independently.

dbo:abstract
  • Das Vogt-Russell-Theorem (oder Russell-Vogt-Theorem) ist ein nach Heinrich Vogt und Henry Norris Russell benannter Zusammenhang in der Astronomie. Es ist auch bekannt als Vogtscher Eindeutigkeitssatz. Es besagt, dass Masse und (chemische) Zusammensetzung eines Sterns eindeutig seinen Radius, seine Leuchtkraft, seine interne Struktur sowie seine Entwicklung im Laufe der Zeit bestimmen. Das Theorem stellt aber nur eine grobe Annäherung an die tatsächlichen Verhältnisse in einem Stern dar und wird heute eher als Faustregel verwendet. (de)
  • Il teorema Vogt-Russell (o teorema Russell-Vogt) è stato enunciato dagli astronomi Heinrich Vogt e Henry Norris Russell. Esso afferma che la massa e la composizione chimica di una stella determinano la sua luminosità, la sua struttura interna e la sua evoluzione. Oggi si ritiene che il teorema rappresenti solo un'approssimazione in quanto altri fattori intervengono, anche se in modo più limitato, nella determinazione dei parametri stellari. (it)
  • 羅素-沃克定理 (Vogt-Russell theorem)是依據海因里希·沃克和亨利·諾利斯·羅素兩人命名的,它的表述是: 質量和化学組成結構是唯一可以斷定恆星半徑、光度和內部結構,以及其後續的演化的因素。 (zh)
