C star carbon star Late type giant with strong bands of carbonated molecules (C₂, CN, CH) and no metallic oxide bands. Formerly they were called R or N types, the R types being the hotter and the N types the cooler C stars.

R star C star Star with spectral characteristics similar to those of K stars except that molecular bands of C₂, CN, and CH are present instead of TiO bands.
