Abstract

We found molecular bands in absorption and in emission in the infrared spectra of the RV Tau stars, R Sct. This is a unique property among the RV Tau stars, but rather commonly seen in Mira variables. The period evolution of this star does not fit with an ordinary post-AGB scenario. Therefore, we argue an alternative choice of the evolutional stage; R Sct is not a post-AGB star but an AGB star in the helium-burning phase of the thermal-pulse cycle
