Searching for Protoplanets in the PDS-201 System with Aperture Masking Interferometry

The disks surrounding young intermediate-mass stars commonly show substructure. A recent adaptive-optics imaging survey of such systems with LBTI/LMIRCam resolved the disk in the PDS-201 system. Evidence from the spectral energy distribution and the new adaptive optics imaging suggests the presence of a large gap in the disk. A leading theory for opening wide gaps in protoplanetary disks includes dynamical interaction with forming giant planets. The architecture of PDS-201 is strikingly similar to the PDS-70 system which includes two imaged accreting planets. We targeted PDS-201 using Aperture Masking Interferometry (AMI) with the LBTI/LMIRCam instrument. AMI allows us to look closer to the star than full aperture adaptive optics imaging, enabling a probe of the disk gap. To analyze the data, we modify both the Amical and the SAMpy AMI data processing pipelines to operate on LMIRCam AMI data. We will report our initial findings.
