Descripción
The authors present a spectroscopic analysis for the gravity
determination of τ Ceti on the basis of a new and high quality set
of data. The iron lines are studied by using the Oxford oscillator
strengths. The results are compared with those obtained with "solar"
oscillator strengths. Non-LTE effects seem to be important in this star.
The Fe I at λ526.955 nm line is used to apply the Blackwell and
Willis (1977) method to determine the surface gravity. The derived log g
is 4.70±0.1.
