Two-fluid dusty shocks: simple benchmarking problems and applications to protoplanetary discs
Andrew Lehmann, Mark Wardle
The key role that dust plays in the interstellar medium has motivated the development of numerical codes designed to study the coupled evolution of dust and gas in systems such as…
The hydroxyl satellite-line `flip' as a tracer of expanding HII regions
Anita Petzler, Joanne R Dawson, Mark Wardle
Observations of the four ~ground state transitions of the hydroxyl radical (OH) have emerged as an informative tracer of molecular gas in the Galactic ISM. W…
The structure of jets launched from post-AGB binary systems
Dylan Bollen, Devika Kamath, Hans Van Winckel +4
We focus on post-asymptotic giant branch (post-AGB) binaries and study the interaction between the different components of these complex systems. These components comprise the post…
X-ray echoes of infrared flaring in Sgr A*
Mark Wardle
Sgr A* exhibits flaring in the infrared several times each day, occasionally accompanied by flaring in X-rays. The infrared flares are believed to arise through synchrotron emissio…
Cosmic snow clouds: self-gravitating gas spheres manifesting hydrogen condensation
Mark Walker, Mark Wardle
We present hydrostatic equilibrium models of spherical, self-gravitating clouds of helium and molecular hydrogen, focusing on the cold, high-density regime where solid- or liquid-h…
Magnetorotational instability in protoplanetary discs
Raquel Salmeron, Mark Wardle
We investigate the linear growth and vertical structure of the magnetorotational instability (MRI) in weakly ionised, stratified accretion discs. The magnetic field is initially ve…
