RESEARCH INTEREST

Professor Yelle studies the atmospheres in our solar system and the atmospheres of extra-solar planets. He analyzes telescopic and spacecraft data and constructs theories and models to determine the composition and structure of atmospheres and their interaction with surfaces and interplanetary space. Current projects include the study of chemical, thermal and dynamical processes in Titan's upper atmosphere using primarily data from the Cassini mission to the Saturn system. He is also investigating escape processes on Titan and extra-solar planets. Yelle is a member of the Cassini Ion Neutral Mass Spectrometer Team and chairperson on the Cassini Titan Atmosphere Model Working Group (TAMWG).
