Edge-on, optically thick circumstellar disks have been imaged at subarcsecond resolution around about a dozen nearby young stellar objects (YSOs). In these systems the central star is occulted from direct view, bright star image artifacts are absent, and the disk reflected light is clearly seen. Comparison of HST edge-on disk images with scattered light models has allowed key structural parameters such as the disk outer radius, vertical scale height, radial flaring profile, total mass, and dust grain properties to be determined. Edge-on disks have been systematically undercounted to date: although 15% of young stars should statistically be occulted by their disk, the observed frequency is < 2%. The Spitzer Space Telescope has provided the first good measurements of the spectral energy distributions for the currently known edge-on disks, finding a characteristic double-peak morphology and showing the sources to be strongly underluminous at wavelengths < 3 microns. Using these as templates, we have identified 70 new edge-on disk candidates among more than 2000 YSOs cataloged in Spitzer legacy surveys of nearby molecular clouds. Twenty-one of these sources are high-confidence identifications with spectroscopic confirmation as YSOs and are optically visible. We propose an R and I band imaging survey of this sample to reveal their disk and jet structures. Image modeling will reveal the full diversity of disk vertical structures that trace the settling of dust grains to the disk midplane - the key first step on the road to planet formation. This program will more than double the number of edge-on disk sources with high-fidelity images suitable for scattered light modeling.

The observations will be made using the ACS/WFC, as it provides better red sensitivity than WFC3/UVIS. I band (F814W) is relatively free of emission lines from Herbig-Haro jets and thus serves as our primary bandpass for imaging scattered light structures. Since some of our sources are likely to possess HH jets, all the targets will also be be imaged on ACS/WFC in the F606W (broad V) filter that captures the Halpha, [S~II], and [O~I] emission lines. In the sources lacking jets, the F606W filter will provide a measurement of dust lane chromaticity that is diagnostic of the grainsize. All of our targets are visible in optical DSS images. As all our targets are red, we baseline a CR-SPLIT 1300 second exposure in F606W and a CR-SPLIT 800 second exposure in F814W. Exposure times have been adjusted slighty from these values to fill the target visibility windows that are available with 50% schedulability. Two targets (SSTGBS110926.1-763333 and SSTC2D163136.8-240419) are sufficiently red that we forgo the F606W images and spend the full orbit imaging in F814W. One object (SSTGBSJ191043.4-365909) is in a binary system with a bright primary star; in this case, we have reduced the long integrations somewhat to make room for short (unsaturated) images of the primary in both filters. There will be a single one-orbit visit for each target. We choose not to dither the CR-SPLIT images, as this would produce slight blurring of the resulting mosaics and hamper our ability to resolve the disk scale heights. Hot pixels will be removed by a local median in our data analysis. Our targets are widely distributed around the sky in the star-forming regions of Perseus (RA= 3h), Taurus-Auriga (4h), Chamaeleon (11h), Lupus (15h), Ophiuchus (16h), and Corona Australis (17h). The target declinations range from -77 to +35. Our sample is thus ``snapshot-like'' and should be easy to schedule. ORIENTS and POS TARGS have been specified for 8 of the visits, in order to place adjacent outflow features on the ACS field of view and to keep diffraction spikes from bright stars off the science targets.
