Open full text 2 citations

Abstract

The discovery of $\sim$ 500 planetary nebulae (PNe) in the bulge region allows us to probe the bulge out to $\sim8$ kpc. This opens up the possibility to track bulge-disc interactions to unprecedented details. We present an exploration of bulge dynamics with Nbody models of a triaxial bulge embedded in an exponential disc (Peyaud 2005).
