Case studies for planetary nebulae with tilted axes.

SAURER W.

Abstract (from CDS):

In this paper we discuss the morphology of two elliptical, point-symmetric planetary nebulae (PNe) with tilted axes: M1-79 and Wei1-5. By means of simple geometry and the assumption of optical thinness in [OIII] we were able to reproduce the observational (morphological) data on these two objects. We have constructed three-dimensional models consisting of an inner and an outer ellipsoid which can account for the overall shape, the tilt of the axes, and the intensity distribution of the PNe when looked at a certain viewing angle. Our results can be interpreted as an indication for a non-circular component of the density distribution within the equatorial plane.
