In this talk I will analyze the BPS spectrum of type II Calabi-Yau compactifications from a four dimensional low energy perspective. I will start with a description of the construction of general, stationary, multicentered BPS solutions of d=4, N=2 supergravity, and explain how they are related to (split) attractor flows in moduli space. These objects turn out to have a surprisingly rich set of features, which I will briefly explore. In the second part of the talk, I will give some examples of applications of this low energy picture to the analysis of the D-brane spectrum of type IIA string theory compactified on the Quintic, including some concrete decay predictions.
