In order to explore efficiently the data from CoRoT it is necessary to ensure that the best and most adequate numerical models are available. Only with state-of-the-art stellar models and their oscillation frequencies will it be possible correctly to extract information from the data to be acquired by CoRoT.

To this end, it is of primary importance to optimise the tools available for Asteroseismology, both in what concerns numerical aspects of the codes, and the fundamental physical ingredients that are used to describe the stars and their oscillations. In order to ensure that the community has the necessary theoretical know-how to explore the data, the tools currently available will be extensively compared, improved, and adapted where necessary.

The CAUP seismology group is deeply involved in the development of tools for Asteroseismology. Our task in CoRoT is to coordinate the efforts of the CoRoT community in the development of evolution and seismic tools. The expertise of the group in CAUP is the use of seismic diagnostics to probe the interior of the star and the atmosphere from observational data such as those expected from CoRoT.
