The aim of my Ph.D. is to find indirect tracers of young multi-planet systems.
Current models of planet formation are only theoretical and are based on interpolation between
observations of the beginning of the process (protoplanetary disks) and the end (fully formed planets).
Young planets are challenging to observe because they are embedded (at least partially) in their stars
accretion disk. In addition, the host stars themselves are also young and thus, highly active.
Until recently there has been no instrument capable of observing the inner regions of young accretion disks.
ALMA, a new radio telescope, will be able to observe the dust in the accretion disks so by numerically modelling
the effects that multiple planets have on the dust we can predict their presence.
