Scientific paper

High resolution spectra of HD 165553, a star reported to be a spectroscopic binary of spectral type F8 Ib are analysed. The stellar parameters - effective temperature, surface gravity and microturbulence are determined using model atmospheres. A detail chemical composition study indicates a near-solar composition for HD 165553. Comparison of its spectrum with that of Cyg, a normal supergiant of spectral type F8 Iab indicates that the star is of a later spectral type; a spectral type G Iab seems more likely for HD 165553.
