Evolution and characteristics of forced shear flows in polytropic atmospheres: Large and small Péclet number regimes
V. Witzke, L. J. Silvers, B. Favier
Complex mixing and magnetic field generation occurs within stellar interiors particularly where there is a strong shear flow. To obtain a comprehensive understanding of these proce…
Mean Flow Evolution of Saturated Forced Shear Flows in Polytropic Atmospheres
V. Witzke, L. J. Silvers
In stellar interiors shear flows play an important role in many physical processes. So far helioseismology provides only large-scale measurements, and so the small-scale dynamics r…
Evolution of forced shear flows in polytropic atmospheres: A comparison of forcing methods and energetics
V. Witzke, L. J. Silvers, B. Favier
Shear flows are ubiquitous in astrophysical objects including planetary and stellar interiors, where their dynamics can have significant impact on thermo-chemical processes. Invest…
Evolutionary graph theory revisited: general dynamics and the Moran process
Karan Pattni, Mark Broom, Jan Rychtar +1
Evolution in finite populations is often modelled using the classical Moran process. Over the last ten years this methodology has been extended to structured populations using evol…
Shear instabilities in a fully compressible polytropic atmosphere
V. Witzke, L. J. Silvers, B. Favier
Shear flows have an important impact on the dynamics in an assortment of different astrophysical objects including accreditation discs and stellar interiors. Investigating shear fl…
Inverse cascade and symmetry breaking in rapidly-rotating Boussinesq convection
B. Favier, L. J. Silvers, M. R. E. Proctor
In this paper we present numerical simulations of rapidly-rotating Rayleigh-Bénard convection in the Boussinesq approximation with stress-free boundary conditions. At moderately lo…
