Abstract

Seismology is the only way to investigate the internal structure of the giant planets, with a lot of scientific implications such as high pressure physics and huge constraints on the scenario of solar system formation. As compared to other existing possibilities (ground based network, spacecraft), seismology of Jupiter will take a maximum benefit from the peculiarities of the Concordia station as an astronomical observatory. Indeed, the continuous temporal coverage for all the winter season, and the quality of the atmospheric seeing, are crucial parameters for this program. The jovian seismometer SYMPA, already used for network observations, is perfectly suitable for Dome C conditions. With the already existing small telescopes deployed in the frame of site testing program, seismology of Jupiter will constitute a excellent intermediate project with high scientific return, before the installation of large telescopes. In a second step, such an instrument could be a first light instrument for a 1.5 m class automatic telescope, which is to be developed as an individual stone for a large interferometer. With this diameter, the same scientific program on Saturn could also be achieved.
