A radio-continuum and photoionization-model study of the two planetary nebulae in the Sagittarius dwarf galaxy
G. Dudziak, D. Pequignot, A. A. Zijlstra +1
Radio continuum observations at 1.4, 4.8 and 8.6 GHz of the two Planetary Nebulae (PNe) in the Sagittarius dwarf galaxy reveal the elongated shape of Wray 16-423 and the extreme co…
High resolution Ks polarization mapping of OH 231.8+4.2 (OH 0739-14) with SOFI
N. Ageorges, J. R. Walsh
The bipolar reflection nebula OH 231.8+4.2 (OH 0739-14), centred on the Mira variable star QX Pup, has been mapped at Ks in linear polarization using the ESO SOFI near-infrared mul…
High resolution near-infrared polarimetry of Eta Carinae and the Homunculus Nebula
J. R. Walsh, N. Ageorges
High resolution near-infrared adaptive optics imaging and polarimetry have been obtained of the Homunculus Nebula and its central star Eta Carinae (HD 93308). Maps of the linear po…
A continuous low star formation rate in IZw 18 ?
F. Legrand, D. Kunth, J. -R. Roy +2
Deep long-slit spectroscopic observations of the blue compact galaxy IZw 18 obtained with the CFH 3.6 m Telescope are presented. The very low value of oxygen abundance previously r…
