Identifier: http://hdl.handle.net/1959.14/362826
Description: There is no conclusive explanation of why ∼80 per cent of planetary nebulae (PNe) are non-spherical. In the Binary Hypothesis, a binary interaction is a preferred channel to form a non-spherical PN. A ... More

Identifier: http://hdl.handle.net/1959.14/271264
Description: We still do not know what causes aspherical planetary nebula (PN) morphologies. A plausible hypothesis is that they are due to the presence of a close stellar or substellar companion. So far, only ~40 ... 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
