Sismologie jovienne : étude des oscillations par photométrie visible et analyse de données spectrométriques

Abstract : Seismology is the best tool to investigate the interior structure of stars and giant planets. The Jovian interior structure remains poorly constrained by observations. This PhD deals with two instrumental projects, dedicated to Jovian seismology: JOVIS, a space photometric project and SYMPA, a multi-site imaging interferometer. The JOVIS concept is to consider Jupiter as a mirror which reflects the solar light. This works shows how the cloud layers react to oscillations and present an amplification of the albedo relative variations by a factor 70. Such amplitude are detectable from space, with high precision photometry. SYMPA's concept is the velocity field quantification, related to the oscillations, by measurement of the Doppler shift. Three campaigns have been done: the performances reach the expected levels and the data analysis is still in progress. At last, we have developed an identification method of the oscillation modes in a noisy signal.
