Application de la spectroscopie à l'étude de la planète Mars et à la recherche de planètes extrasolaires :
caractérisation des spectromètres de l'instrument SPICAM-Light embarqué à bord de la mission spatiale Mars-Express ; développement et optimisation du spectromètre astronomique EMILIE dédié aux mesures de vitesses radiales stellaires.

Abstract : This thesis deals with three innovating techniques of spectrometry, one in near infrared, the other into visible, and the third in ultraviolet ray. Two of them are used by the instrument Spicam-Light on board the Mars-Express spacecraft, for the study of the Martian atmosphere. The third relates to spectrometry with high resolution since the ground, and is dedicated to the stellar radial velocity measurements for the search of extrasolar planets at the Haute-Provence Observatory (France) with the Absolute Astronomical Accelerometer.
The study presents the original concept of the UV and NIR spectrometers of the Spicam-Light instrument, through a detailed technical description. It brings results, calibrations, photometric estimates before the takeoff and the flight performances. The study on the Absolute Astronomical Accelerometer explains the significant instrumental development of this device. It brings results to illustrate its actual and futures possibilities.
