From Bipolar to Elliptical: Simulating the Morphological Evolution of Planetary Nebulae
From Bipolar Elliptical: Simulating Morphological Evolution Planetary Nebulae
2011/9/27
The majority of Proto-planetary nebulae (PPN) are observed to have bipolar morphologies. The majority of mature PN are observed to have elliptical shapes. In this paper we address the evolution of PPN...
