The next step in the model comparison

2/10Priorities

Following the work during the workshops (Nice and Aarhus) it is now time to prepare the results to be presented in the next CoRoT Week 9 in ESTEC.

We must concentrate on the following key objectives:

• Complete Task 1 on model comparisons,

• Initiate Task 2 on frequency comparisons,

• Present the results at ESTEC.

The work to be completed over the next few weeks should be planned having these objectives in mind.

also a presentation about ESTA to the Seismology Working

Group.


4/10Reports for the CoRoT Community

1) Oral presentation: Status and achievements of ESTAPresentation to the Seismology Working Group on what has been done up to now on ESTA and the plans for the near future. The objective is to show everyone that ESTA is very active and productive!

2) Report on Task1 (poster): Results of the model comparison

Summary of the main results for Task 1. It should not be a detailed report but instead a grand summary of the outcome of this exercise.

3) Report on Task 2 (poster): Preliminary results of the frequency comparison

Report on the preliminary results for the frequency comparison covering the first step of this exercise.

4) Reports on comparisons (oral & poster): Results of specific comparisons

Detailed comparisons between specific codes (evolution or seismic) should also be presented on pairs of codes and on specific targets/items of particular interest.

All information and data will be available on the ESTA website:

http://www.astro.up.pt/corot/

The presentations and reports of this meeting will also be made available.

The development of tools for exchanging models and supporting the computation of the frequencies will continue. Please send all information that can be relevant for extending as much as possible these tools.

Stay tuned and continue calculating models and producing results on comparisons…

See you in ESTEC!
