The spatial orientations of bipolar nebulae.

PHILLIPS J.P.

Abstract (from CDS):

We investigate the spatial orientation of mass outflow axes in post-main-sequence bipolar nebulae. As a consequence, some 71% of nebulae are found to have their outflow axes oriented within ±45o of the Galactic plane; a distribution which has a probability level of 5.8x10–4. There appear to be no clear mechanisms whereby such a non-random distribution may be explained.
