Unifying Transport Models of Thermohaline Convection in Stars
Valentin A. Skoutnev
Thermohaline convection is a standard chemical mixing process in stellar interiors, yet its mixing efficiency is not fully settled. Competing theories predict turbulent diffusion c…
Inefficiency of chiral dynamos in protoneutron stars and the early universe
Valentin A. Skoutnev, Andrei M. Beloborodov
The chiral plasma instability (CPI) has been invoked as a possible mechanism for generating primordial magnetic fields in the universe and ultrastrong fields in neutron stars. We i…
The stability of propagating plane inertial waves in rotating fluids
Valentin Skoutnev, Aurélie Astoul, Adrian J. Barker
Inertial waves transport energy and momentum in rotating fluids and are a major contributor to mixing and tidal dissipation in Earth's oceans, gaseous planets, and stellar interior…
Magnetic Webs in Stellar Radiative Zones
Valentin A. Skoutnev, Andrei M. Beloborodov
Rotational evolution of stellar radiative zones is an old puzzle. We argue that angular momentum transport by turbulent processes induced by differential rotation is insufficient,…
Zones of Tayler Instability in Stars
Valentin A. Skoutnev, Andrei M. Beloborodov
The Tayler instability (TI) of toroidal magnetic fields is a candidate mechanism for driving turbulence, angular momentum (AM) transport, and dynamo action in stellar radiative zon…
Tayler Instability Revisited
Valentin A. Skoutnev, Andrei M. Beloborodov
Tayler instability of toroidal magnetic fields is broadly invoked as a trigger for turbulence and angular momentum transport in stars. This paper presents a systematic revisi…
Critical Balance and Scaling of Strongly Stratified Turbulence at Low Prandtl Number
Valentin A. Skoutnev
We extend the scaling relations of stably stratified turbulence from the geophysical regime of unity Prandtl number to the astrophysical regime of extremely small Prandtl number ap…
On large-scale dynamos with stable stratification and the application to stellar radiative zones
Valentin Skoutnev, Jonathan Squire, Amitava Bhattacharjee
Our understanding of large-scale magnetic fields in stellar radiative zones remains fragmented and incomplete. Such magnetic fields, which must be produced by some form of dynamo m…
Scaling of Small-Scale Dynamo Properties in the Rayleigh-Taylor Instability
Valentin Skoutnev, Elias R. Most, Amitava Bhattacharjee +1
We derive scaling relations based on free-fall and isotropy assumptions for the kinematic small-scale dynamo growth rate and amplification factor over the course of the mixing, sat…
Small-Scale Dynamo in Stably Stratified Turbulence
Valentin Skoutnev, Jonathan Squire, Amitava Bhattacharjee
We present numerical investigations into three principal properties of the small-scale dynamo in stably stratified turbulence: the onset criterion, the growth rate, and the nature…
Noise-Induced Magnetic Field Saturation in Kinetic Simulations
J. Juno, M. Swisdak, J. M. TenBarge +2
Monte Carlo methods are often employed to numerically integrate kinetic equations, such as the particle-in-cell method for the plasma kinetic equation, but these methods suffer fro…
Boundary-induced effect on the spoke-like activity in ExB plasma
Eduardo Rodriguez, Valentin Skoutnev, Yevgeny Raitses +3
The spoke instability in an Penning discharge is shown to be strongly affected by the boundary that is perpendicular to field lines. The instability is the stronges…
Temperature-dependent Saturation of Weibel-type Instabilities in Counter-streaming Plasmas
V. Skoutnev, A. Hakim, J. Juno +1
We present the first 2X2V continuum Vlasov-Maxwell simulations of interpenetrating, unmagnetized plasmas to study the competition between two-stream, Oblique, and filamentation mod…
