On a stochastic model for the spin-down of solar type stars
Nicolas Leprovost, Eun-Jin Kim
Modeling the rotation history of solar-type stars is still an unsolved problem in modern astrophysics. One of the main challenges is to explain the dispersion in the distribution o…
Turbulent transport and dynamo in sheared MHD turbulence with a non-uniform magnetic field
Nicolas Leprovost, Eun-Jin Kim
We investigate three-dimensional magnetohydrodynamics turbulence in the presence of both a large-scale velocity and non-uniform magnetic field. By assuming a turbulence driven by a…
Dynamo efficiency with shear in helical turbulence
Nicolas Leprovost, Eun-Jin Kim
To elucidate the influence of shear flow on the generation of magnetic field (the dynamo effect), we study the kinematic limit where the magnetic field does not backreact on the ve…
Analytical theory of forced rotating sheared turbulence. The Parallel case
Nicolas Leprovost, Eun-Jin Kim
Forced turbulence combined with the effect of rotation and shear flow is studied. In a previous paper [Leprovost and Kim, PRE in press (2008)], we considered the case where the she…
A turbulent model of torque in von Karman swirling flow
Nicolas Leprovost, Louis Marié, Bérengère Dubrulle
A stochastic model is derived to predict the turbulent torque produced by a swirling flow. It is a simple Langevin process, with a colored noise. Using the unified colored noise ap…
Dynamo quenching due to shear flow
Nicolas Leprovost, Eun-Jin Kim
We provide a theory of dynamo ( effect) and momentum transport in three-dimensional magnetohydrodynamics. For the first time, we show that the effect is severely reduced by…
