Oral title: Sparse aperture masking and mm interferometry of transition disks: the planet-disk dilemma

Oral abstract: I would like to present sparse aperture masking observations of a protoplanetary disk, that show both multi epoch 
detections consistent with a point source around the central star, and a change in position angle during the lapse of ~1 year. We 
used ALMA to model the disk and we found there is synergy between NIR and mm interferometry and the disk that needs to be 
accounted for in SAM observations.
