WebThe Hertzsprung-Russell (H-R) diagram is an analog to the periodic table of the elements. It was discovered that when the absolute magnitude (M V) – intrinsic brightness – of stars is plotted against their surface temperature (stellar classification) the stars are not randomly distributed on the graph but are mostly restricted to a few well-defined regions. WebEn astronomie, le diagramme de Hertzsprung-Russell, en abrégé diagramme H-R, est un graphique dans lequel est indiquée la luminosité d'un ensemble d' étoiles en fonction de leur température effective. Ce type de diagramme a permis d'étudier les populations d'étoiles et d'établir la théorie de l' évolution stellaire .
