Scientific paper

Observations show that some protoplanetary disks present a cavity, that is a wide depletion from the star to a distance of several AUs. The question whether this can be caused by a planet is here addressed. After a review of the nature of planet-disk interactions, we show that planets may open cavities. However, this process is very difficult to simulate numerically. We present a new algorithm well adapted to the study of this problem. Finally, we study the influence of cavity opening on planetary migration and we show how the latter can be stopped.
