weak G-band star comparison table

Subject has surface temperature is a kind of has luminosity class has spectral type has definition has color

G star 5000 to 6000 K late star cooler than G2 Yellowish star in which the H and K lines of Ca II have become dominant and in which a tremendous profusion of spectral lines of both neutral and ionized metals, particularly iron, begins to show. The Balmer lines of hydrogen are still recognizable. Examples are the Sun and Capella. yellowish

giant greater than 1000 Kelvin star III High-luminosity star that lies above the main sequence on the Hertzsprung-Russell diagram.

weak G-band star 5000 to 6000 K giant III cooler than G2 G-type giant (G5 to K5) with a very weak or absent G band of CH and weak CN bands. These stars are C-deficient. yellowish
