The goal of the EU-funded SPIDI project is to predict and detect the signature of inner planets still embedded in the circumstellar disk of young stars, in a region where the inner disk’s edge interacts with the strong magnetic field of the central star. Indeed, the Kepler satellite has revealed that the most common occurrence of exoplanetary systems in the Solar neighbourhood consists of compact chains of super-Earths and mini-Neptunes orbiting their host star at short distances (<0.4 au, Porb < 100 days). Where do these inner planets come from? How do they form? How do they interact with the star and the disk? These are some of the questions the SPIDI project addresses. Every member of the SPIDI core team (see authors above) will provide a summary of the work completed during the project, which combines state-of-the-art modeling (MHD and radiative transfer) and various observational approaches (interferometry, spectropolarimetry, photometry) to tackle these issues. The special format of the presentation (9 speakers, 5 min each) will provide the audience with an overview of what has been done so far in the project and what remains to be done to reach the expected science goals.
