Abstract

Based on imaging and spectroscopic data, we develop a 3D model for the Huygens Region of the Orion Nebula. θ¹ Ori C, the hottest star in the Trapezium, is surrounded by a wind-blown Central Bubble that opens SW into the Extended Orion Nebula. Outside of this feature lies a layer of ionized gas at about 0.4 pc from θ¹ Ori C. Both of these features are moving rapidly away from θ¹ Ori C with an expansion age for the Central Bubble of only 15,000 yr.
