Title: The Inner Oort Cloud Population

Abstract: The Kuiper Belt population has an outer edge at about 50 AU. Sedna and our recent discovery, 2012 VP113, are the only known objects with perihelia significantly beyond this edge at about 80 AU. These inner Oort cloud objects obtained their orbits when the solar system was vastly different from now. There are several theories as to the origin of these objects that can only be tested by finding several more. This population is likely larger than the Kuiper Belt but previous surveys did not go faint enough, did not have the required long cadence, or covered too small of sky area to find them. The dynamical and physical properties of objects in this region offer key constraints on the formation and evolution of our solar system. We propose to continue our survey with DECam in order to find several more inner Oort cloud objects to further constrain formation theories and thus learn about our Sun's formation environment and evolution.
