SUMMARY:Planetary systems in the making: interactions between multiple pla
 nets and their parent disc - Farzana Meru (ETHZ)

DESCRIPTION:As the number of exoplanet detections is increasing it is beco
 ming clearer that systems with multiple planets are common.  The interacti
 ons between multiple planets and their parent disc are much more dynamic a
 nd complex than those between a single planet and the disc.  We perform tw
 o-dimensional hydrodynamical simulations to explore the evolution of T Tau
 ri discs which have multiple planets embedded in them.  We present prelimi
 nary results on the disc structures\, the flow of material and the gap pro
 perties that are present as a consequence of the presence of multiple plan
 ets.  If the disc structures are long-lived and can persist for long perio
 ds of time\, they may well be features that can be observed with new spati
 ally-resolved disc observations.
