Shaping Planetary Nebulae,ssful models are two-dimensional interacting stellar wind models for which the PN nucleus is assumed to originally expel much or most of its mass in an equatorial waistband. The physics of the ensuing evolution seems to be explained nicely by a combination of hydrodynamics coupled with time-dependen

Shock Modelling of Planetary Nebulae,y our analysis to the Planetary Nebulae NGC 6905 and NGC 6537. A detailed spectroscopic study of these objects reveals the existence of high nuclear velocities, together with complex kinematic structures and unusual emission line intensities. Shock ionization clearly plays a key role in these nebula

First Wavelet Analysis of Emission Line Variations in Wolf-Rayet Stars, powerful, objective technique of wavelet analysis. Results for the substructures in one WR star so far show that the scaling laws between (a) flux and velocity dispersion and (b) lifetime and flux, combined with (c) their mass spectrum, strongly support the hypothesis that we are seeing the high ma

Herbig Ae/Be Stars,m. After a historical introduction, we briefly review their optical and UV spectroscopic properties. We consider the evidence for and against disks around Herbig Ae/Be stars; the existence of which remains highly controversial. We also examine in-depth their interaction with the surrounding medium a

Radiatively Driven Winds Using Lagrangian Hydrodynamics,can only be applied to simple geometries. Presented here are preliminary results of a particle based Lagrangian code (applied to a simple 1D radiatively driven wind test case), which will be able to resolve structure down to the smallest scales without becoming temporally prohibitive. This approach

Parametric determination of the inclination of Keplerian circumstellar discs from spectropolarimetrcircumstellar disc are presented. It is shown that analysis of the scattered line profiles at different wavelengths which, due to Doppler redistribution, sample different disc regions allows the disc inclination to be determined.
