    The turbulent destruction of interstellar clouds

    The interaction of an astrophysical shock with a cloud typically occurs at high Reynolds number, and in such cases will be highly turbulent. However, the formation of fully developed turbulence is usually prev...

    Cautionary Tails

    We briefly discuss the observational evidence for linear features in diffuse astronomical sources. We then discuss their formation either by radiation shadowing or by hydrodynamic processes.

    Self-Similar Evolution of Remnants With Conductively Driven Mass-Loading

    We present self-similar solutions for remnants that are mass-loaded by conductively driven evaporation. This work extends the earlier results of Chièze and Lazareff through the inclusion of the explicit depend...

    The Fine Structures of Planetary Nebulae

    Most theoretical studies of the dynamics of planetary nebulae assume that the slow ejecta from the red-giant or asymptotic giant branch phase of evolution of the central star is distributed smoothly. We consid...

    Truncated Collimated Flows in Abell 30, Abell 78 and the Honeycomb Nebula

    Localised collimated flows of ionized gas are found in two hydrogen deficient planetary nebulae, Abell 30 and Abell 78 as well as in the Honeycomb complex of interlocking shells in halo of 30 Dor in the Large ...

    Structure and Stability of Ionization Fronts

    The study of the dynamics of ionization fronts has moved far since Franz Kahn helped define the field in the 1950s. Nevertheless, the stability of the fronts and the nature of elephant trunks and bright rims i...

    Some Recent Results on MHD Shocks and Winds

    Work on the rotation of the magnetic field around the shock propagation direction in an oblique shock in a dusty medium is reviewed. A significant observational consequence is that the rotation lowers the mini...

    The Tails of Externally Illuminated Young Stellar Objects in the Orion Nebula

    Recent observations of externally illuminated young stellar objects in the Orion Nebula show that they have a variety of morphologies. In particular, long thin tails which terminate in points have been observe...

    Low-Mass Versus High-Mass Star Formation

    Structures like the clumps identified in the CO maps of the Rosette Molecular Cloud and the dense cores such as those in B5, a cluster of cores and young low-mass stars, are key to considerations of star forma...

    Wide intermediate scale structures in mass-loaded flows

    We showed in earlier work that a clump embedded in tenuous plasma, which is flowing subsonically relative to the clump, will develop a long thin tail whether the gas in the tail behaves adiabatically or isothe...
