A Consolidated Online Database of Galactic Planetary Nebulae
B. Miszalski, A. Acker, F. Ochsenbein +1
Since the unifying Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (SECGPN) a large number of new discoveries have been made thanks to improved surveys and discovery techniq…
A catalogue of integrated Hα fluxes for ~1100 Galactic planetary nebulae
I. S. Bojicic, D. J. Frew, Q. A. Parker
We present new determinations of the integrated Hα flux for ~1100 Galactic planetary nebulae measured from the Southern H-Alpha Sky Survey Atlas (SHASSA) and its northern counterpa…
A barium-rich binary central star in Abell 70
Henri M. J. Boffin, B. Miszalski, D. J. Frew +4
We have found the central star of Abell 70 (PN G038.1-25.4, hereafter A 70) to be a binary consisting of a G8 IV-V secondary and a hot white dwarf. The secondary shows enhanced Ba…
A barium central star binary in the Type-I diamond ring planetary nebula Abell 70
B. Miszalski, H. M. J. Boffin, D. J. Frew +4
Abell 70 (PN G038.1-25.4, hereafter A 70) is a planetary nebula (PN) known for its diamond ring appearance due a superposition with a background galaxy. The previously unstudied ce…
A pilot study of the radio-continuum emission from MASH planetary nebulae
I. S. Bojičić, Q. A. Parker, D. J. Frew +3
We report an Australia Telescope Compact Array (ATCA) radio-continuum observations of 26 planetary nebulae (PNe) at wavelengths of 3 and 6 cm. This sample of 26 PNe were taken from…
