cds-question@unistra.frgiant-starsspectroscopychemically-peculiar-starsWe present the first results of a new abundance survey of the Milky Way bulge based on Keck HIRES spectra of 27 K giants in the Baade's Window (l=1{deg},b=-4{deg}) field. The spectral data used in this study are of much higher resolution and signal-to-noise ratio than previous optical studies of Galactic bulge stars. The [Fe/H] values of our stars, which range between 1.29 and +0.51, were used to recalibrate large low-resolution surveys of bulge stars. Our best value for the mean [Fe/H] of the bulge is -0.10+/-0.04. This mean value is similar to the mean metallicity of the local disk and indicates that there cannot be a strong metallicity gradient inside the solar circle. The metallicity distribution of stars confirms that the bulge does not suffer from the so-called G dwarf problem. This paper also details the new abundance techniques necessary to analyze very metal-rich K giants, including a new Fe line list and regions of low blanketing for continuum identification.2006ApJ...636..821Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/636/821CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/89/636 : Giant M stars in Baade's Window (Blanco+, 1984)J/AJ/110/1774 : K giants in Baade's window (Terndrup+ 1995)J/AJ/112/171 : K Giants in Baade's Window.
