The luminosity class II in the Yerkes spectral classification is given to bright giants. These are stars which straddle the boundary between giants and supergiants, and the classification is in general given to giant stars with exceptionally high luminosity, but which are not sufficiently bright or massive to be classified as supergiants.
Well known stars which are classified as bright giants include:
- Epsilon Canis Majoris (Adhara): a blue-white (B-type) bright giant
- Theta Scorpii (Sargas): a white (F-type) bright giant
- Beta Capricorni (Dabih): a yellow-white (G-type) bright giant
- Alpha Hydrae (Alphard): an orange (K-type) bright giant
- Alpha Herculis (Rasalgethi): a red (M-type) bright giant
- Gamma Canis Majoris (Muliphein) a (B-Type) bright giant
Famous quotes containing the words bright, giant and/or stars:
“I’d give all wealth that years have piled,
The slow result of Life’s decay,
To be once more a little child
For one bright summer-day.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“In frames as large as rooms that face all ways
And block the ends of streets with giant loaves,
Screen graves with custard, cover slums with praise
Of motor-oil and cuts of salmon, shine
Perpetually these sharply-pictured groves
Of how life should be.”
—Philip Larkin (1922–1986)
“Throw the children into the river; civilization has given us too
many.
It is better to die than to grow up and find that you are colored.
Pluck the stars out of the heavens. The stars mark our destiny. The
stars marked my destiny.
I am tired of civilization.”
—Fenton Johnson (1886–1958)
