Webb28 okt. 2024 · The temperature of stars are plotted against their luminosity, and the color of stars (spectral type) against their absolute magnitude. Hertzsprung-Russell Diagram … WebbStars can be classified by their surface temperatures as determined from Wien's Displacement Law, but this poses practical difficulties for distant stars. Spectral characteristics offer a way to classify stars which gives information about temperature in a different way - particular absorption lines can be observed only for a certain range of ...
