SUMMARY:ITC Colloquium - Martin Pessah (NBI)
DESCRIPTION:<div>	"Migration of Low-mass Planets in Dusty Protoplanetary Disks"<br><br>Fast inward migration of planetary cores embedded in gaseous<br>disks is a common problem in the current planet formation paradigm. Even<br>though dust is ubiquitous in protoplanetary disks, its dynamical role in<br>the migration history of planetary embryos has not been considered until<br>recently. In this talk, I will show that the scattered pebble-flow<br>induced by a low-mass planetary embryo leads to an asymmetric<br>dust-density distribution that is able to exert a net torque. Building<br>on the results or a large suite of numerical simulations for measuring<br>this dust torque under a wide range of conditions, I will present the<br>first study showing that dust torques can have a significant impact on<br>the migration and formation history of planetary embryos</div><div class="yj6qo">	 </div><div class="adL">	 </div>
