Based on Spitzer selected YSOs, we present a study of transition disks located in Lupus. Several mechanismshave been proposed to explain their defining characteristic: an inner opacity hole and an optically thick outerdisk. These processes are: planet formation, grain growth, photoevaporation, tidal truncation in close binaries.We have carried out Adaptive Optics (AO) imaging, submillimeter photometry, and Echelle spectroscopy inorder to observationally characterize our transition disk sample. With the analysed data we can distinguish thefour scenarios and identify candidate transition disk systems that are currently forming planets. Such objectsare excellent targets to be followed-up with Herschel and ALMA.
