Chemical Abundances Of Red Giant Stars In The Globular Cluster M107 (Ngc 6171), Julia O'Connell, Christian I. Johnson, Catherine A. Pilachowski, Geoffrey Burks Sep 2011

Chemical Abundances Of Red Giant Stars In The Globular Cluster M107 (Ngc 6171), Julia O'Connell, Christian I. Johnson, Catherine A. Pilachowski, Geoffrey Burks

Mathematical Sciences Faculty Research

We present chemical abundances of Al and several Fe-Peak and neutron-capture elements for 13 red giant branch stars in the Galactic globular cluster NGC 6171 (M107). The abundances were determined using equivalent width and spectrum synthesis analyses of moderate-resolution ( R ∼ 15,000), moderate signal-to-noise ratio (〈S/N〉 ∼ 80) spectra obtained with the WIYN telescope and Hydra multifiber spectrograph. A comparison between photometric and spectroscopic effective temperature estimates seems to indicate that a reddening value of E(B - V) = 0.46 may be more appropriate for this cluster than the more commonly used value of E(B - V) = 0.33. …
