Chemical Homogeneity in the Hyades

De Silva, Gayandhi; Sneden, Chris; Paulson, D B; Asplund, Martin; Bland-Hawthorn, Joss; Bessell, Michael; Freeman, Kenneth

Description

We present an abundance analysis of the heavy elements Zr, Ba, La, Ce, and Nd for Hyades F-K dwarfs based on high-resolution, high signal-to-noise ratio spectra from Keck HIRES. The derived abundances show the stellar members to be highly uniform, although some elements show a small residual trend with temperature. The rms scatter for each element for the cluster members is as follows: Zr = 0.055, Ba = 0.049, Ce = 0.025, La = 0.025, and Nd = 0.032 dex. This is consistent with the measurement...[Show more]
