Subject has synonym has spectral type has definition

barium star Ba II star Peculiar low-velocity, strong lined red-giant stars of spectral types G, K, and M, with abnormally large abundances of heavy s-process (but not r-process) elements. They are usually regarded as old disk stars of ~ 1-2 M_sun.

S star cooler than G2 Late type giant (K5 to M) showing distinct bands of ZrO.
