The interaction of planetary nebulae and their AGB progenitors with the interstellar medium
Interaction with the Interstellar Medium (ISM) cannot be ignored in understanding planetary nebula (PN) evolution and shaping. In an effort to understand the range of shapes observed in the outerExpand
Vortices in the Wakes of Asymptotic Giant Branch Stars
Vortices have been postulated at a range of size scales in the universe, including at the stellar-size scale. While hydrodynamically simulating the wind from an asymptotic giant branch (AGB) starExpand
It’s a Wonderful Tail: The Mass-Loss History of Mira
Recent observations of the Mira AB binary system have revealed a surrounding arclike structure and a stream of material stretching 2° away in opposition to the arc. The alignment of the proper motionExpand
Vortices in the wakes of AGB stars
Vortices have been postulated at a range of size scales in the universe including at the stellar size-scale. Whilst hydrodynamically simulating the wind from an asymptotic giant branch (AGB) starExpand
VLT/near-infrared integral field spectrometer observations of molecular hydrogen lines in the knots of the planetary nebula NGC 7293 (the Helix Nebula)
Knots are commonly found in nearby planetary nebulae (PNe) and star-forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding theExpand
Detached shells as tracers of asymptotic giant branch-interstellar medium bow shocks
New Spitzer imaging observations have revealed the structure around the Mira variable star R Hya to be a one-sided parabolic arc 100 arcsec to the west, stretching from north to south. WeExpand
The shaping of planetary nebula Sh 2-188 through interaction with the interstellar medium
Sh2-188 is an example of strong interaction between a planetary nebula (PN) and the interstellar medium (ISM). It shows a single arc-like structure, consisting of several filaments, which isExpand
Forward and inverse cascades in decaying two-dimensional electron magnetohydrodynamic turbulence
Electron magnetohydrodynamic (EMHD) turbulence in two dimensions is studied via high-resolution numerical simulations with a normal diffusivity. The resulting energy spectra asymptotically approach aExpand
Hall cascades versus instabilities in neutron star magnetic fields
Context. The Hall effect is an important nonlinear mechanism affecting the evolution of magnetic fields in neutron stars. Studies of the governing equation, both theoretical and numerical, have shownExpand
A composite equation of state for the modeling of sonic carbon dioxide jets in carbon capture and storage scenarios
The development of a novel composite two-phase method to predict the thermodynamic physical properties of carbon dioxide (CO) above and below the triple point, applied herein in the context ofExpand
