At the very end of its growth, Jupiter became surrounded by a circumplanetary disk (CPD) in which the Galilean moons formed. How these moons formed remains an outstanding question. We aim to model the chemical evolution of this CPD to establish a connection between the moons’ surface compositions measured by the Juice and Europa-Clipper spacecrafts to disentangle between the existing formation scenarios. To do, so we develop a 2D circum-planetary disk model, designed to form the backbone of the chemical model that will follow the gas phase evolution of all species of interest. Our disk structure is based on the work Heller et al (2015) [1], with some key improvements at the level of the description of the opacity. Our disk’s parameters have also been scaled to those observed recently in the CPD around the exoplanet PDS70c. Here we present the CPD structure and display some preliminary results regarding the chemical evolution of C- and N- dominated species in the gas phase of the CPD.
