Scientific paper

We present a new modeling tool for planetary nebulae (PNe), based on 3D photoionization calculations. From models for two theoretical PNe, we show that the enhancement in the equatorial zone observed in several PNe is not necessarily due to a density gradient, as usually interpreted. We study the morpho-kinematic properties of the PN NGC 3132 and show that a bipolar Diabolo shape successfully reproduces the observed images, as well as the high resolution observations.
