Scientific paper

Debris disks are one of the final stages in the evolution of planetary systems. High resolution imaging of debris disks has been instrumental to our understanding of the status of planet formation in these systems. The detection of clumps and asymmetries has even led to the detection of unseen planets. However, just six resolved disks exist in the literature. Eta Crv is now the seventh debris disk confirmed with imaging, and was discovered in a recent sub-mm survey of nearby stars. Its proximity {18 pc} and similarity to Beta Pic, one of the "big four" Vega-type disks, makes it an excellent candidate for a high resolution coronagraphic study of its disk structure. Modeling of this structure at many wavelengths will set hard constraints on its unseen planetary system and the distribution of particles from micron to kilometer in size, thus significantly extending our understanding of the planet formation processes in debris disks
