Modeling the cometary structure of the planetary nebula HFG1 based on the evolution of its binary central star V664 Cas
Monthly Notices of the Royal Astronomical Society(2016)
摘要
HFG1 is the first well-observed planetary nebula (PN) which reveals a cometary-like structure. Its main morphological features consist of a bow-shaped shell, which surrounds the central star, accompanied by a long collimated tail. In this study, we perform two-dimensional hydrodynamic simulations modelling the formation of HFG1 from the interaction of the local ambient medium with the mass outflow...
