Characterizing the AB Doradus Moving Group Via High Resolution Spectroscopy and Kinematic Traceback

We present a detailed analysis of 10 proposed F and G members of the nearby, young moving group AB Doradus (ABD). Our sample was obtained using the 2.7m telescope at the McDonald Observatory with the coude echelle spectrograph, achieving R 60,000 and S/N 200. We derive spectroscopic Teff , log(g), [Fe/H], and microturbulance (vt) using a bootstrap method of the TGVIT software resulting in typical errors of 33K in Teff , 0.08 dex in log(g), 0.03 dex in [Fe/H], and 0.13 km s 1 in vt. Characterization of the ABD sample is performed in three ways: (1) Chemical homogeneity, (2) Kinematic Traceback, and (3) Isochrone tting. We nd the average metal abundance is [M/H] = -0.03 0.06 with a traceback age of 125 Myrs. Our stars were t to 3 dierent evolution
