Wave-Mediated Boundary Layers of Accretion Discs: Role of Internal Structure of the Accretor
Samuel G. D. Turner, Roman R. Rafikov, Alexander A. Philippov
Disc accretion onto astrophysical objects with a material surface proceeds through the boundary layer (BL) -- a radially narrow region in the inner disc where the incoming gas must…
The turbulent variability of accretion discs observed at high energies
Andrew Mummery, Samuel G. D. Turner
We use numerical stochastic-viscous hydrodynamic simulations and new analytical results from thin disc theory to probe the turbulent variability of accretion flows, as observed at…
A new 2D stochastic methodology for simulating variable accretion discs: propagating fluctuations and epicyclic motion
Samuel G. D. Turner, Christopher S. Reynolds
Accretion occurs across a large range of scales and physical regimes. Despite this diversity in the physics, the observed properties show remarkably similarity. The theory of propa…
Investigating the Theory of Propagating Fluctuations with Numerical Models of Stochastic Accretion Discs
Samuel G. D. Turner, Christopher S. Reynolds
Across a large range of scales, accreting sources show remarkably similar patterns of variability, most notably the log-normality of the luminosity distribution and the linear root…
Modelling the distributions of white dwarf atmospheric pollution: a low Mg abundance for accreted planetesimals?
Samuel G. D. Turner, Mark C. Wyatt
The accretion of planetesimals onto white dwarf atmospheres allows determination of the composition of this polluting material. This composition is usually inferred from observed p…
