Description
TTVs provide an excellent resource to probe the dynamics of resonant exoplanet systems and characterize the masses of transiting planets. However, the masses of transiting planets can be biased by the presence of non-transiting planets in the system, leading to outliers of $ >5 \sigma$. Although existing robustness criteria based on mass and eccentricity priors work well for systems with only transiting planets, they are unable to consistently identify the effect of non-transiting perturbers. Using a set of simulated systems from the data challenge of the Geneva Resonant State Workshop, this poster presents the process of developing criteria to ensure the accuracy of transiting planet masses regardless of non-transiting perturbers in the system.
