S-Type stars
S-type stars are cool giants
which show evidence of bands of ZrO in their spectra (4641A, 4620A,
5304A, 5379A, 5551A). The TiO bands are also visibles and some time,
strong hydrogen emission lines due to shock waves in pulsating atmosphere.
This stars are often variables of many type. The Mira-type is the
major population.
