Resource Type: conference paper
Identifier: http://hdl.handle.net/1959.14/345009
Description: There is no quantitative theory to explain why a high 80% of all planetary nebulae are non-spherical. The Binary Hypothesis states that a companion to the progenitor of a central star of planetary neb ... More

Identifier: http://hdl.handle.net/1959.14/283845
Description: We use photoionization modeling to assess the binary nature of the central stars of NGC 2392 and NGC 6026. If they are close binaries, they are potential Type Ia supernovae (SNe Ia) progenitors if the ... More

Identifier: http://hdl.handle.net/1959.14/208180
Description: During the past 20 years, the idea that non-spherical planetary nebulae might need a binary or planetary interaction to be shaped was discussed by various authors. It is now generally agreed that the ... More

Identifier: http://hdl.handle.net/1959.14/200164
Description: The ionizing star of the planetary nebula NGC 2392 is too cool to explain the high excitation of the nebular shell, arid an additional ionizing source is necessary. We use photoionization modeling to ... More

Identifier: http://hdl.handle.net/1959.14/119439
Description: As an adjunct to the planetary nebula (PN) search from the AAO/UKST Hα survey, a visual search was conducted for new emission nebulae from the SHASSA and VTSS surveys, outside a Galactic latitude of | ... More

Identifier: http://hdl.handle.net/1959.14/119442
Description: Accurate emission line fluxes from planetary nebulae (PNe) provide important constraints on the nature of the final phases of stellar evolution. Large, evolved PNe may trace the latest stages of PN ev ... More

Identifier: http://hdl.handle.net/1959.14/118905
Description: The recent on-line availability of large-scale, wide-field surveys of the Galaxy and Magellanic Clouds in several optical and near/mid-infrared passbands has provided unprecedented opportunities to re ... More

Identifier: http://hdl.handle.net/1959.14/42080
Description: IPHAS is an ongoing Hα imaging survey of the North Galactic plane. When completed, it is expected to discover several hundred new Galactic planetary nebulae, in addition to a huge number of Hα emitter ... More
