It is the summer, and it feels like I am getting lots done! That said, I only got in a small amount of serious research time today. I spent most of it commenting on a draft manuscript from Price-Whelan on chaos in the halo of the Milky Way. Yes, dynamical chaos. This is the coming to fruition of a pretty old idea at CampHogg: What is the difference between stellar streams on regular orbits and those on chaotic orbits? It turns out that the differences are bigger than we expected!
