About My Thesis

My thesis is primarily focused with understanding the behavior of planetary rings. In particular, edges where there is no moon interacting with the edge to somehow shape or constrain the edge. This is sort of the basic case for ring edges, so understanding this simplest situation is a necessary step towards understanding all ring edges. Why to edges matter, you ask? Because the edges of rings ultimately govern how quickly rings can spread, which in turn sets the how long rings live. Also, we see many very "sharp" edges in rings, even when there is no obvious way to keep the edge sharp. ("Sharp" for these purposes means that the ring ends abruptly in space rather than fading out over a large (many kilometers) distance.)
