dc.description.abstract	IRAS 10215-5916 was classified as a post-AGB star and also as a massive red supergiant. It was also found to be a spectroscopic binary. In our high resolution spectra we found molecular features from a cool star of Teff = 3750K. We also see the spectral signature of a relatively hotter star of Teff = 7250K. We found that both the components of the binary system are metal poor. From the theoretical spectrum synthesis we obtained [C/H] = -0.2 +/- 0.4, [O/H] = -1.0 +/- 0.4 and [Fe/H] = -2.0 +/- 0.5 for the hot component of the binary system. The enhanced carbon abundance and metal poor characteristics show that the hot component of the binary system could be a post-AGB star.	en
