A study into the kinematics and binary-induced shaping of the bipolar PN HaTr 4
Abstract
HaTr 4 is a compact bipolar planetary nebula with a binary central star. We present data analysis from VLT-UVES longslit echelle spectra, focusing on [OIII]5006.84 A emission emanating from the central star system. By combining narrowband imagery with high spectral and spatial resolution position-velocity arrays, it was possible to create a spatio-kinematical model of HaTr 4 and hence futher constrain its morphology, expansion velocity, kinematical age, and nebular inclination in relation to that of the binary.
