Which 4 Properties Does The Hr Diagram Used To Classify Stars

Spectral Class (Color)–Sun-G2 3. Temperature 4. Absolute Magnitude– (How bright it appears because of its size) How many TYPES of stars are shown on the HR Diagram?

In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis. This can be expressed as a ratio of the star’s luminosity to that of the Sun; L */L sun.

The third possible scale for the horizontal axis is a star’s spectral class. By splitting the light from a star through a spectrograph its spectrum can be recorded and analysed. Stars of similar size, temperature, composition and other properties have similar spectra and are classified into the same spectral class.
