F star 6000 to 7500 K early star O, B, A, and early F Star of spectral type F in which lines of hydrogen and Ca II are of about equal strength. Metal lines also become noticeable. yellow-white

supergiant greater than 1000 Kelvin star I An extremely luminous star of large diameter and low density. No supergiants are near enough to establish a trigonometric parallax.

post-asymptotic branch star 6000 to 7500 K F star I F-type supergiant with strong sulfur lines. yellow-white
