Orientation effects in Bipolar nebulae
We show that the inclination to the line of sight of bipolar nebulae strongly affects some of their observed properties. We model these objects as having a spherically symmetric Planetary Nebula and a dusty equatorial density enhancement that produces extinction that varies with the viewing angle. Our sample of 29 nebulae taken from the literature shows a clear correlation between the inclinati...
متن کاملNarrow - Band Imaging of Bipolar Planetary Nebulae
We present near-IR narrow-band continuum-subtracted images in the H2 2:122 m, and Br 2:166 m emission lines for a sample of 15 bipolar planetary nebulae. H2 emission was definitely detected for most of the objects in this sample (13 out of 15). The very high H2 detection rate supports the idea that bipolar planetary nebulae have important reservoirs of molecular material and offer suitable phys...
متن کاملThe formation of bipolar planetary nebulae
Using a radiation-hydrodynamics code I follow the formation of planetary nebulae around stars of different mass. Because a more massive central star evolves much faster than a lower mass one, it is to be expected that this will affect the formation of the PN. For the stars I use the evolutionary tracks for remnants with masses of 0.605 M⊙ and 0.836 M⊙, taken from Blöcker (1995). The AGB wind is...
متن کاملMolecules in bipolar proto - planetary nebulae ⋆
Two bipolar proto-planetary nebulae, IRAS16594-4656 and IRAS17150-3224, have been detected in various molecular lines, namely CO, 13CO, HCN and CN, and remain undetected in several other species. CO(J=2-1) and CO(J=3-2) line profiles are compared to new spectra of similar PPN candidates, previously undetected in CO(J=2-1): CPD-53◦5736, IRAS17106-3046, IRAS17245-3951 and IRAS17441-2411. CO(J=2-1...
متن کاملCO content of bipolar planetary nebulae
We report high-sensitivity millimeter-wave CO observations of recently discovered bipolar planetary nebulae (PNe). Three objects (BV 5-1, K 3-94 and K 3-24) have been detected, and one of them (BV 5-1) is resolved by the ∼10′′ telescope beam. The envelopes of the three newly detected objects display values of the molecular to ionized mass ratio of ∼ 0.2, and sizes of ∼ 0.1 pc. This indicates th...
