Abstract

High resolution spectra of a magnified bulge star were obtained at the 8 m Kueyen VLT-UT2 telescope with the UVES spectrograph. The source is a bulge giant of baseline magnitude , magnified to . These data allow us to derive the stellar parameters of effective temperature  K, gravity log , reddening , metallicity and and [O/Fe] ≈ 0.0 for EROS-BLG-2000-5. The giant appears to be located in the far side of the bulge.
