Title: Mid-IR Exploration of an Edge-On Protoplanetary Disk

Abstract: We propose multi-wavelength T-ReCS mid-IR imaging of the central region of the Herbig Ae/Be star VV Serpens. This dramatic system has an edge-on disk that is casting a shadow across the much bigger envelope extending out to thousands of AU. Our sub-arcsec images are key to a full interpretaion of a whole range of other observations including extensive Spitzer imaging and spectroscopy, and they will provide serious constraints on disk models. In particular, the imaging proposed observations of VV Ser will permit us to: 1. Determine the disk size at mid-IR wavelengths; 2. Examine the disk column density along lines of sight of different z; 3. Study how the interface zone where the disk ?surface? and the inner envelope merge, and thereby probe the detailed relationship of disk and envelope; 4. Characterize the amount of flaring as a function of distance from the star; and 4. Estimate the dust temperature versus distance from the star for both the disk surface and inner envelope.
