WebbThe Hertzsprung-Russell diagram (H-R diagram) is a useful diagram that captures the statistical distribution of stars regarding their luminosities and temperatures. The main … WebbAstronomers classify stars according to temperature with the hottest stars designated as 'O' stars, the next hottest stars as 'B' stars, the next hottest 'A' and so on, following the scheme O,B,A,F,G,K, and M. The letter assigned to a star is termed its spectral class. Each of the seven spectra corresponds to one of the classes of stars.

WebbThe Hertzsprung–Russell diagram, abbreviated as H–R diagram, HR diagram or HRD, is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures. The diagram was created independently in 1911 by Ejnar Hertzsprung and by Henry Norris ... Webb15 mars 2024 · Here is the intensity-wavelength graph for the Sun. As the surface temperature of a hot body such as a star increases: the intensity of radiation it emits increases
