We go further and analyzed the detectability possibilities of hypothetical exoplanets in coorbital motion from synthetic RV signals, considering different types of stable planar configurations, orbital eccentricities and mass ratios. For each nominal solution corresponding to small-amplitude oscillations around the periodic solution, we generate a series of synthetic RV curves mimicking the stellar motion around the barycenter of the system. We then fit the resulting data sets and we compare the resulting residuals with different models. Finally we estimated orbital parameters and also analyzed the dynamics of fitted system. Later we identified formation scenarios for such type of orbits with the 2D public hydro-code FARGO.
