Spatio-kinematic modelling of the double-shelled PN Abell 65
Abstract
Abell 65 is one of the few planetary nebulae known to contain a binary central star, and as such represents an opportunity to investigate the effect of binarity on nebula formation and evolution. Deep imaging and high-resolution echelle spectroscopy, in conjunction with spatio-kinematic modelling, reveal the bipolar nature of Abell 65 and importantly a nebular inclination consistent with that of the central binary, indicating that the binary may have played a dominant role in the shaping of the nebula. Furthermore, the data reveal the presence of two nebular shells, each with similar morphologies and inclinations, but not co-eval in nature (with the outer-shell being kinematically older).
