答案：【计分规则】: Astronomers have determined the spectral type and luminosity of a large number of stars. Danish astronomer Herzbrunn and American astronomer Russell first studied the distribution of stars on the spectrum. They take the star's spectral type as the abscissa and the star's absolute magnitude as the ordinate. This map is called the "spectral photometry of stars" or the hologram of stars, often written as the H-R map. This map plays an important role not only in the classification of stars, but also in studying the evolution of stars.Any answer related to it is ok.
