New Planerary Nebulae towards the Galactic bulge
P. Boumis, S. Akras, P. A. M. van Hoof +3
New Planetary Nebulae (PNe) were discovered through an [O III] 5007 A emission line survey in the Galactic bulge region with l>0 deg. We detected 240 objects, including 44 new PNe.…
The PNLF distance to the Sculptor Group galaxy NGC 55
G. C. Van de Steene, G. H. Jacoby, C. Praet +2
We identified 21 new Planetary Nebula (PN) candidates in the Sculptor Group galaxy NGC 55. We determined a most likely distance of 2.00 +/- 0.2 Mpc using the Planetary Nebulae Lumi…
Radio and submillimetre observations of wind structure in zeta Pup
R. Blomme, G. C. Van de Steene, R. K. Prinja +2
We present radio and submillimetre observations of the O4I(n)f star zeta Pup, and discuss structure in the outer region of its wind (~ 10-100 R*). The properties of bremsstrahlung,…
Near-infrared and Br_gamma observations of post-AGB stars
G. C. Van de Steene, P. A. M. van Hoof, P. R. Wood
We investigate the infrared properties of the IRAS sources not confirmed as PNe in Van de Steene & Pottasch (1993). We observed 28 objects in the N-band of which 20 were detected a…
Two New Planetary Nebulae Discovered in a Galaxy Search in the Southern Milky Way
R. C. Kraan-Korteweg, A. P. Fairall, P. A. Woudt +1
Spectroscopic observations have been carried out for eleven objects believed to be planetary nebulae on the basis of their optical appearance. They were discovered in an ongoing de…
