A Rich new vein of planetary nebulae from the AAO/UKST H-alpha survey
International Astronomical Union Symposium (209th : 2001) (19 - 23 November 2001 : Canberra)
Kwok, Sun; Dopita, Mike and Sutherland, Ralph. Planetary nebulae : their evolution and role in the universe : proceedings of the 209th Symposium of the International Astronomical Union held at Canberra, Australia, 19-23 November 2001, p.25-31
We report on an unprecedented source of Planetary Nebulae (PN) discovered from AAO /UKST Ha survey images of the Southern Galactic Plane. A pristine region of PN discovery space is being sampled due to the excellent depth, coverage, resolution and uniformity of the Ha survey. Large numbers of new PN are being found ("' 1000 so far). They are typically more evolved, obscurred and of lower surface brightness than in most other surveys. The doubling of known PN should have a significant impact on many aspects of PN research.
