Seasonal evolution of ${\mathrm{C}}_2{\mathrm{N}}_2$, ${\mathrm{C}}_3{\mathrm{H}}_4$, and ${\mathrm{C}}_4{\mathrm{H}}_2$ abundances in Titan's lower stratosphere

We study the seasonal evolution of Titan's lower stratosphere (around 15~mbar) in order to better understand the atmospheric dynamics and chemistry in this part of the atmosphere.…
