Abstract

Using high resolution spectra from the ELODIE database the atmosphere of the yellow supergiant HD 159378 was analyzed. Its effective temperature of 7500 K, much higher than previously considered, was found. The star seems to be a young F-supergiant with slightly enhanced metallicity, not a post-AGB star or a long-period Cepheid as was thought before. The metallicity of HD 159378 is in accordance with its 6 kpc galactocentric position in the Galactic disk.
