We summarize a selection process to identify red giants in the direction of the southern warp of the Galactic disk, employing VI C photometry and multiobject spectroscopy. We also present results from follow-up high-resolution, high signal-to-noise echelle spectroscopy of three field red giants, finding [Fe/H] values of about -0.5. The field stars, with galactocentric distances estimated at 10-15 kpc, support the conclusion of Yong and coworkers that the Galactic metallicity gradient disappears...[Show more]
