In human astronomy, stellar classification was a classification of stars based on their spectral characteristics. The spectral class was the designated class of a star, describing the ionization of its chromosphere, what atomic excitations were most prominent in the light, giving an objective measure of the temperature in this chromosphere.
Spectral classes[]
Class A[]
- The KCR-125-06 quaternary system had a class A primary. (DF)
- The Yildun System contained a class A1 star. (CS1)
Class F[]
- The trinary Cerberus System contained a class F4 star (Cerberus-A). (HH8)
- The Congo System contained a class F6 star. (CS1)
- The Darius System contained a class F6 star. (HH12)
- The binary Gregor System contained a class F9 star (Gregor-A). (HH6)
- The trinary Secour System contained a class F9 star (Secour-A). (HH8)
