The Fine Structures of Planetary Nebulae

Most theoretical studies of the dynamics of planetary nebulae assume that the slow ejecta from the red-giant or asymptotic giant branch phase of evolution of the central star is distributed smoothly. We consider briefly the observational evidence for small scale structure in both neutral and ionised...

Description
Summary:Most theoretical studies of the dynamics of planetary nebulae assume that the slow ejecta from the red-giant or asymptotic giant branch phase of evolution of the central star is distributed smoothly. We consider briefly the observational evidence for small scale structure in both neutral and ionised PNe gas, examine some of the ways it can be generated and describe some of the consequences of its presence.[PUBLICATION ABSTRACT]
