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…
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…
Twisted magnetic structures emerging from buoyancy instabilities
L. Jouve, L. J. Silvers, M. R. E. Proctor
We here report calculations of magnetic buoyancy instabilities of a sheared magnetic layer where two separate zones are unstable. The idea is to study the possible generation of la…
How can large-scale twisted magnetic structures naturally emerge from buoyancy instabilities?
B. F. N. Favier, L. Jouve, W. Edmunds +2
We consider the three-dimensional instability of a layer of horizontal magnetic field in a polytropic atmosphere where, contrary to previous studies, the field lines in the initial…
