the plasma resistivity η, kinematic viscosity ν, and electron number density ne are derived. A …

Magnetorotational instability, current relaxation, and current-vortex sheet

FEM Silveira, RMO Galvão - Physics of Plasmas, 2013 - pubs.aip.org
The conjugate effect of current relaxation and of current-vortex sheet formation on the
magnetorotational instability is explored in a conducting fluid. It is found that the relative …

Rayleigh-Taylor instability with finite current relaxation

FEM Silveira, HI Orlandi - Physics of Plasmas, 2016 - pubs.aip.org
In this work, we explore the influence of perturbative wavelengths, shorter than those usually
considered, on the growth rate of the Rayleigh-Taylor modes. Therefore, we adopt an …

Inertial Effects on Tearing Instability

FEM Silveira - PLASMA PHYSICS AND TECHNOLOGY, 2016 - ojs.cvut.cz
In this work, we explore inertial effects, due to charged species in a resistive plasma, on the
tearing instability. The standard theory of tearing modes assumes a long wavelength limit. At …
