DESCRIPTION:Saturn’s moon Titan is the only moon of the Solar System to 
 possess a dense atmosphere\, quite similar to Earth’s atmosphere in its 
 composition (mainly nitrogen)\, its thermal structure\, and its methane cy
 cle analogous to Earth’s water cycle. Titan’s atmosphere hosts a compl
 ex photochemistry\, which produces many hydrocarbons (e.g C2H6\, C4H2\, C6
 H6...) and nitriles (such as HCN\, or HC3N) which react further together t
 o form organic hazes (particles in suspension in the atmosphere).  Like Ea
 rth\, Titan’s atmosphere undergoes seasonal variations of insolation ove
 r its orbit around the Sun (29.5 years)\, which are expected to affect its
  temperature and composition. \nDuring almost half a Titan year (2004-2017
 )\, the Cassini spacecraft monitored Titan’s atmosphere\, hence providin
 g us with an unprecedented opportunity to study its climate and its season
 al evolution from northern winter to summer solstice. In this seminar\, I 
 will present the new insights on Titan’s atmospheric chemistry and dynam
 ics gained from the Cassini mission and how they shape current and future 
 studies of Titan’s atmosphere.\n
