Characterization of the multiple planetary system Kepler-279 using Transit Time Variations

I characterized the multi-planet system Kepler-279, exploiting the TTV (Transit Time Variation) signals to determine orbital parameters and planetary masses. I ran three sets of simulations with TRADES (TRAnsits and Dynamics of Exoplanetary Systems), a Python code that, during the orbital integration, calculates the transit times and compares them with the observations, allowing the modelling of the dynamic of the system.
