The luminosity class II in the Yerkes spectral classification is given to bright giants. These are stars which straddle the boundary between ordinary giants and supergiants, based on the appearance of their spectra.[1]
Example bright giants
Well known stars which are classified as bright giants include:
- Alpha Carinae (Canopus): a white (A-type) bright giant
- Epsilon Canis Majoris (Adhara): a blue-white (B-type) bright giant
- Omicron Scorpii: a white (A-type) bright giant
- Theta Scorpii (Sargas): a white (F-type) bright giant
- Beta Draconis: a yellow (G-type) bright giant
- Beta Capricorni (Dabih): an orange (K-type) bright giant
- Alpha Herculis (Rasalgethi): a red (M-type) bright giant
- Gamma Canis Majoris (Muliphein) a (B-Type) bright giant
