[110.10] The Chemical Composition of the Remote Disk Cluster Tombaugh 2

J.A. Brown (U. Washington), G. Wallerstein (U. Washington), D. Geisler (CTIO)

We have obtained high-resolution ($\lambda / \Delta \lambda \sim 34,000$) CTIO 4-meter echelle-CCD spectra of three red giants in the remote anti-center disk cluster Tombaugh 2. Our preliminary results indicate a mild metal deficiency, $[Fe/H] \sim -0.3$, for a reddening of about $E(B-V) = 0.3-0.4$. Results for one star indicate a greater deficiency of oxygen than of iron or $\alpha$-elements. Full results for all three stars will be presented.
