Summary

SPIDI\'s goal is to discover inner planets at the time they form in the circumstellar disks of stars at the very beginning of their life. This requires to develop numerical simulations of star-planet-disk interactions and predict what observable signatures nascent planets would offer to astronomers. Going to the telescope, the goal is then to detect those signatures and constrain the properties of proto-planets to better understand the origin of our own Solar System and other planetary systems that are now known to be ubiquitous in the Galaxy.

Work performed

MHD and radiative transfer code development and preliminary numerical computations have started and, in parallel, several international observing campaigns have been performed on specific targets using the largest telescopes (e.g. ESO/VLTI). Within a few months, the numerical and observational approaches will converge and provide the first constraints on inner nascent planets in young stellar systems.

Final results

This is the first time star-disk-planet interaction are computed in numerical models and their observational signatures predicted. It is also the first time that multiple observational approaches have been combined simultaneously (interferometry, spectropolarimetry, space photometry) to scrutinize young stellar systems. These unique advances ought to provide the best route towards the detection of inner planets still in the process of formation.
