Abstract

In this talk, I review how four dimensional stationary supergravity solutions that are more general than spherically symmetric black holes emerge naturally in the low energy description of BPS states in type II Calabi-Yau compactifications. An explicit construction of multicenter solutions using single center attractor flows as building blocks is presented, and some interesting properties of these solutions are examined. We end with a brief remark on non-BPS configurations.
