Infrared study of the two categories of S stars
Abstract
Photometric observations of 20 Tc-deficient and 24 Tc-rich S stars in the near infrared are presented in this paper. With the IRAS data, infrared two color diagrams, IRAS low-resolution spectra and energy distributions are discussed to summarize the way to segregate Tc-rich stars from Tc-deficient ones.
