A collimated, ionized bipolar structure and a high density torus in the young planetary nebula IRAS 17347-3139
D. Tafoya, Y. Gomez, N. A. Patel +5
We present observations of continuum (lambda = 0.7, 1.3, 3.6 and 18 cm) and OH maser (lambda = 18 cm) emission toward the young planetary nebula IRAS 17347-3139, which is one of th…
The Unusual Distributions of Ionized Material and Molecular Hydrogen in NGC 6881: Signposts of Multiple Events of Bipolar Ejection in a Planetary Nebula
G. Ramos-Larios, M. A. Guerrero, L. F. Miranda
The planetary nebula NGC 6881 displays in the optical a quadrupolar morphology consisting of two pairs of highly collimated bipolar lobes aligned along different directions. An add…
Spectral index of the H2O-maser emitting planetary nebula IRAS 17347-3139
J. F. Gomez, I. de Gregorio-Monsalvo, J. E. J. Lovell +5
We present radio continuum observations of the planetary nebula (PN) IRAS 17347-3139 (one of the only two known to harbour water maser emission), made to derive its spectral index…
Study of the properties and spectral energy distributions of the Herbig AeBe stars HD 34282 and HD 141569
B. Merín, B. Montesinos, C. Eiroa +5
We present a study of the stellar parameters, distances and spectral energy distributions (SEDs) of HD 34282 and HD 141569, two pre-main sequence Herbig AeBe stars. Both objects ha…
The triple-shell structure and collimated outflows of the planetary nebula NGC 6891
M. A. Guerrero, L. F. Miranda, A. Manchado +1
Narrow-band H and [N {\sc ii}] images and high-dispersion spatially-resolved echelle spectroscopy of the planetary nebula NGC 6891 are presented. These observations show a great…
