The structure of NGC 6309: BRET or bipolar outflow?

Multiwavelength and multitechnique observations towards NGC 6309 are presented. The data consist of lambda3.6-cm continuum, ground and space-based imaging, and high and low-dispersion longslit spectra. The structure of the central region seems to be a distorted, ring of 20' in diameter. The lack of [N(II)] emission is conspicuous, as revealed by imaging and low dispersion spectra. Notably, the kinematics of the point-symmetric (PS) structures of NGC 6309 indicates the presence of lobes or cavities as those generally found in bipolar nebulae. The results lead to conclude that the origin of this peculiar morphology is not related to BRETs, but rather to that of a bipolar PN with PS structures in its lobes.
