Abstract:
Distant astrophysical objects like planetary nebulae can normally only be observed from a single point of view, which makes deducing plausible 3D models a hard task that usually involves a lot of manual work [Nadeau et al. 2001]. However, additional physical assumptions can be used in order to estimate the missing depth information. In previous work [Wenger et al. 2009], a certain axial symmetry was assumed which is present in many planetary nebulae, so that tomographic methods could be used for the reconstruction. However, this assumption obviously fails for many of the most complex and interesting objects in question, and it only leads to unambiguous results as long as no absorption occurs within the nebula.
