CN-strong star comparison table

Subject is a kind of has luminosity class has spectral type has definition

giant star III High-luminosity star that lies above the main sequence on the Hertzsprung-Russell diagram.

late star star cooler than G2 Star with spectral type later than the sun (G2).

CN-strong star giant III cooler than G2 Late type giant with strong CN bands. Metallic lines are also stronger than in normal giants.
