The periodic eclipsing properties of the pre-main-sequence binary, KH 15D, are currently predicted to be the result of a circumbinary ring that is inclined to the orbital plane, which causes the system to be occulted. Using a collection of data that includes radial velocity measurements, a decade worth of detailed photometry, and a scattered assortment of archival photometry dating back to the 1950s, we attempt to confirm this theoretical model and further explain the detailed properties of KH 15D's light curve. Particularly, we seek to explain the gradual slope directly preceding total eclipse as well as the slight rise in flux at mid-eclipse. Our chosen explanation is that these features are caused by an intrinsic property of the dust that results in the forward scattering of the light from the binary.
