A detailed review of the models for the star Hydri is done
by adjusting the evolutionary sequences to the most recent
bolometric, spectroscopic and astrometric data.
The dependence of the solution on some of the relevant
modelling parameters is analysed and the degeneracy of the
solution using the HR Diagram analysis discussed.
We briefly analyse how the seismic study of the star can help
to clarify some of the degeneracy of the model solutions.
Preliminary results on the fundamental parameters of
Hydri are presented
and the expected seismic behaviour of the star described.
