Color/symbol conventions
The colors and the shapes of the symbols in the diagrams are related to the spectral
classification of the star.
Luminosity class V | Luminosity class III | ||
Luminosity class III, log(Teff)>3.85 and log(g)>3.2 | Luminosity class II | ||
Luminosity class I | Wolf-Rayet stars |
