Abstract
We have studied the IRAS-LRS spectra of the unidentified (optically) stellar source IRAS 18530+0817. The far-infrared observations of this source show flux and spectral variability in the 8–60 µm region within a period of six months, as well as unusual spectral features. We have also obtained and analysed near and mid-infrared spectra (1–3 µm) which illustrate that this object possesses strong H 2 O, CO and CO 2 absorption lines. Our observations indicate that IRAS 18530+0817 has the characteristics of an evolved late type red giant and that most likely it is an AGB star surrounded by an oxygen-rich envelope.
