Searching for hidden planets in debris disks

Once the tumultuous stage of planet formation completed, fully formed exoplanets and rocky debris material known as 'debris disc' are left to coexist. However this coexistence is not always as peaceful as it seems. Planets can gravitationally interact with their debris disc and induce significant asymmetries. With the improving resolution of observations, the number of spectacular images of asymmetric debris discs is increasing. Could each debris disc host a hidden planet responsible for carving the disc asymmetric features? This thesis investigates this question by numerically modeling the disc-planet interaction in order to reproduce the observed disc asymmetries.
