Adventures in High Angular Resolution Astrophysics.

While large numbers of exoplanets have been discovered in the past two decades, it has become apparent that many, if not most, did not actually form where they are currently found, and so cannot tell us a great deal about how planetary systems form. For that we must turn our attention to planet-building disks around very young stars. Here we may have the opportunity to see protoplanets or their effects just as these bodies are forming. Unfortunately, the direct detection of protoplanets orbiting young stars is made difficult by the brightness of the host star and the small angular distances the protoplanets will often have from their host. However, a number of techniques that allow us to probe closer to the star are being deployed in the search. In some cases we may be seeing the effects the protoplanets are having on their natal disks, while in others we may be able to directly detect the protoplanets themselves. In this talk I will describe some of the current efforts to make these detections.
