carbon star | late star | In the HD system, a rather loose category of peculiar red-giant star, usually of spectral types R and N, whose spectra show strong bands of C2, CN, or other carbon compounds and unusually high abundances of lithium. Carbon stars resemble S stars in the relative proportion of heavy and light metals, but they contain so much carbon that these bands dominate their spectra. (C2,0. The number following the comma is an abundance parameter.) |
CS star | carbon star | Star exhibiting combined characteristics of C- and S-type stars - i.e. the presence of both C2 and ZrO bands. |
