La mission spatiale Rosetta a étudié la comète 67P/Churyumov-Gerasimenko (67P/C-G) pendant deux ans, d'août 2014 à septembre 2016. A bord de la sonde, l'expérience ROSINA était composée de deux spectromètres de masse (DFMS et RTOF) pour étudier la composition des neutres et des ions présents dans la coma, et d'un senseur de pression (COPS) pour mesurer la densité et la vitesse du gaz cométaire. Le travail présenté a pour objectif l'étude de la coma de la comète 67P/C-G grâce à l'analyse et l'interprétation des données de l'instrument RTOF, en particulier des mesures des principaux volatiles (H2O, CO2 et CO) et de leurs abondances relatives. Les mesures récoltées pendant les deux années de mission nous permettent d'étudier les variations diu...
