Abstract
To understand about Gould Belt, we intend to study chemical abundances for two young open clusters - IC 2391 which is a member of Gould Belt and NGC 6475 which is not. UVES POP (Ultraviolet and Visual Echelle Spectrograph Paranal Observatory Project) provides the spectra of twelve stars in IC 2391 and five stars in NGC 6475 with spectral resolution R of 80,000. In this study, we have determined the stellar parameters (Teff, logg, metallicity, and microturbulant velocity) using Fe I and Fe II lines. The equivalent widths of iron lines have been measured by TAME. The results of stellar parameters are presented.
