This proposal aims at using the queue-mode 1.3m telescope at CTIO to gather near-contemporaneous photometric measurements of a sample of objects that will be observed with the Herschel Space Observatory in the upcoming months as part of the Open Time Key Program GASPS. This project is aimed at characterizing the gas content of circumstellar disks around young stars throughout the planet formation phase. In order to model the Herschel data in a coherent manner, it is necessary to determine each star's basic properties (effective temperature, mass, luminosity), which implies obtaining a complete broadband spectral energy distribution to combine with existing longer data (AKARI, Spitzer, Herschel and millimeter single-dish and interferometric fluxes). Here we propose to obtain new simultaneous optical and IR photometric measurements of 16 targets that cannot be observed from Northern observatories. In addition to provide a sound basis for our disk modeling effort, the observations proposed here will also offer new insight on the location, morphology and evolution of the disks' inner rim in conjunction with the currently ongoing AKARI observations.
