| Abstract | Spectra of the Hyades K0 giants Tau and Tau in the regions 5852-5864 ˚ A and 6145-6176 ˚ A have been recorded at high resolution and with signal/noise in the range 150-250. A critical comparison reveals that, although nearly all lines in the observed regions have a similar depth, lines of Tau are broader by about 10% than those of Tau. An LTE analysis indicates that slightly higher turbulent broadening in Tau can account for the observed differences in line-width. Study of two particularly temperature sensitive features confirms earlier observations that the effective temperature of Tau is less than that of Tau and determines the temperature difference to be 80 20 K. |
