REPORT ON THE COROT EVOLUTION AND SEISMIC TOOLS ACTIVITY

We present the work undertaken by the Evolution and Seismic Tools Activity (ESTA) team of the CoRoT Seis-mology Working Group. We have focused on two main tasks: Task 1 – now finished – has aimed at testing, com-paring and optimising seven stellar evolution codes which will be used to model the internal structure and evolu-tion of the CoRoT target stars. Task 2, still underway, aims at testing, comparing and optimising different seis-mic codes used to calculate the oscillations of models for different types of stars. The results already obtained are quite satisfactory, showing minor differences between the different numerical tools provided the same assumptions on the physical parameters are made. This work gives us confidence on the numerical tools that will be available to interpret the future CoRoT seismic data
