A very low-research day was saved by Suroor Gandhi (NYU) who showed me work she is doing with Melissa Ness (Columbia) on stellar chemistry and kinematics. We discussed the question of whether the Milky Way stellar halo really looks like a distinct kinematic and chemical component (as it should!) or whether it just looks like some kind of continuous extension of the disk (which it should not, but does). Interesting, and how to dig deeper?
