HD 61005 is the first resolved debris disk to show clear evidence for interaction with the interstellar medium and thus presents a unique testbed for probing environmental theories of disk evolution, including sandblasting, interstellar gas drag, and ram pressure stripping of disk gas. I will present results of our new multi-wavelength program initiated to characterize this source. Results to date include (1) optical coronagraphic polarization images, which resolve the source into two distinct morphological components, (2) scattered-light colors, which constrain the grain size distribution, (3) 1.3-mm interferometric observations, which reveal a ring of large grains near the outer edge of the swept back structure, (4) mid-infrared images, which resolve a warm interior asteroid belt, and (5) a high-resolution optical echelle spectrum, which limits the ambient ISM density to that typical of local interstellar clouds. The latter result suggests that the evolutionary state of HD 61005 represents a commonplace, intermittent stage of debris disk evolution driven by interaction with typical, low-density clouds. I will discuss the implications of this result in the context of models of interaction with low-density interstellar gas developed for the Solar System. The models predict the relative flow direction is oriented along the disk midplane in the plane of the sky; scheduled near-UV absorption spectroscopy observations will test this prediction. In addition to presenting our specific results for HD 61005, I will discuss the morphological features these models can produce in general, and suggest a few additional systems in which they may be relevant.
