Scattered light signatures of flyby-induced warps in protoplanetary discs
Katie L. Milsom, Tim J. Harries, C. J. Nixon
We explore the observational signatures of flybys in scattered light images of protostellar discs. The warps are modelled using 1D warp propagation theory coupled to a fast radiati…

On the origin of anomalous dissipation in simulations of tidal disruption events
Chris Nixon, Eric R. Coughlin, Zachary L. Andalman
In a tidal disruption event (TDE), a star is destroyed by the tidal field of a supermassive black hole. The stellar debris is initially placed on highly elliptical orbits, and a lo…

On the isotropy of viscosity in accretion discs
Chris Nixon, Jim Pringle
Accretion discs are fundamental to many astrophysical systems, providing the conversion of gravitational potential energy into radiation that we can observe. In many systems there…
