Fig. 5


Luminosity-effective temperature diagram constructed for the components of 66 Eri with the evolutionary calculations by Girardi et al. (2000). The thin solid curves represent the original evolutionary tracks, while thick curves show the tracks interpolated for the final component masses. The dotted line shows the isochrone for log t = 7.47 yr. The vertical dashed line corresponds to mean effective temperature of the components, Teff    =    11   000 K.
