The central stars of the planetary nebulae NGC 7027 and NGC 6543 ?
Infrared spectra of NGC 7027 and NGC 6543 ranging from 2.4 to 45 m were obtained with the Short Wavelength Spectrometer on board the Infrared Space Observatory. A first analysis of these spectra, with the aid of photo-ionization models, is presented. We report the first detection of the [Arvi] 4.53 m and [Nevi] 7.65 m lines in the spectrum of NGC 7027. When compared with older observations it i...
متن کاملImaging and Spectroscopy of the Planetary Nebula NGC 6778
We present narrow-band images and long-slit echelle spectra of the planetary nebula (PN) NGC6778. The data show this PN as bipolar, with a very prominent low-excitation equatorial toroid, highexcitation lobes and two pairs of collimated outflows. Morphologically, the pairs of outflows are different from each other; one is linear and oriented along the bipolar axis, the other presents an S-shape...
متن کاملAbundances in planetary nebulae: NGC 2792
The mid-infrared spectrum of the rather circular planetary nebula NGC 2792 taken with the Spitzer Space Telescope is presented. This spectrum is combined with the ultraviolet IUE spectrum and with the spectrum in the visual wavelength region to obtain a complete, extinction corrected, spectrum. The chemical composition of the nebula is then calculated in two ways. First by directly calculating ...
متن کاملBaltic Astronomy BINARY CENTRAL STARS OF PLANETARY NEBULAE
This paper reviews our knowledge on binary central stars of planetary nebulae and presents some personal opinions regarding their evolution. Three types of interactions are distinguished: type I, where the binary companion induces the mass loss; type II, where it shapes the mass loss but does not enhance it; type III, where a wide orbit causes the centre of mass to move, leading to a spiral emb...
متن کاملX - ray Imaging of Planetary Nebulae with Wolf - Rayet - type Central Stars : Detection of the Hot Bubble in NGC 40
We present the results of Chandra X-ray Observatory (CXO) observations of the planetary nebulae (PNs) NGC 40 and Hen 2-99. Both PNs feature late-type Wolf-Rayet central stars that are presently driving fast (∼ 1000 km s), massive winds into denser, slow-moving (∼10 km s) material ejected during recently terminated asymptotic giant branch (AGB) evolutionary phases. Hence, these observations prov...
