Annotations

comment: "A number of different luminosity classes are distinguished:
* I supergiants
Ia-0 (hypergiants or extremely luminous supergiants (later addition)), Example: HD 183143 (spectrum is B6-8 Ia-0)
Ia (luminous supergiants), Example: Deneb (spectrum is A2Ia)
Iab (intermediate luminous supergiants)
Ib (less luminous supergiants), Example: Betelgeuse (spectrum is M2Ib)
* II bright giants
IIa, Example: Scuti (HD 173764) (spectrum is G4 IIa)
IIab Example: HR 8752 (spectrum is G0Iab:)
IIb, Example: HR 6902 (spectrum is G9 IIb)
* III normal giants
IIIa, Example: Persei (spectrum is M4 IIIa)
IIIab Example: Reticuli (spectrum is M2 IIIab)
IIIb, Example: Pollux (spectrum is K2 IIIb)
* IV subgiants
IVa, Example: Reticuli (spectrum is K1-2 IVa-III)
IVb, Example: HR 672 A (spectrum is G0.5 IVb)
* V main sequence stars (dwarfs)
Va, Example: AD Leonis (spectrum M4Vae)
Vb, Example: 85 Pegasi A (spectrum G5 Vb)
* VI subdwarfs (rarely used)
* VII white dwarfs (rarely used)" (string)
