DIFFUSION OF MAGNETIC FIELD AND REMOVAL OF MAGNETIC FLUX FROM CLOUDS VIA TURBULENT RECONNECTION
(IOP PUBLISHING LTD, 2010)
The diffusion of astrophysical magnetic fields in conducting fluids in the presence of turbulence depends on whether magnetic fields can change their topology via reconnection in highly conducting media. Recent progress ...
Magnetic reconnection in two-dimensional magnetohydrodynamic turbulence
(American Physical Society, 2009-12)
Systematic analysis of numerical simulations of two-dimensional magnetohydrodynamic turbulence reveals the presence of a large number of X-type neutral points where magnetic reconnection occurs. We examine the statistical ...
Properties of magnetic reconnection in MHD turbulence
(American Institute of Physics, 2010-03)
Numerical simulations of two-dimensional Magnetohydrodynamic (2D MHD) turbulence reveal the presence of a huge number of sites where magnetic reconnection locally occurs. The properties of this ensemble of reconnection ...
Complexity of magnetic-field turbulence at reconnection exhausts in the solar wind at 1 au
(IOP, 2021)
Magnetic reconnection is a complex mechanism that converts magnetic energy into particle kinetic energy and
plasma thermal energy in space and astrophysical plasmas. In addition, magnetic reconnection and turbulence
appear ...
Rapid alignment of velocity and magnetic field in magnetohydrodynamic turbulence
(American Physical Society, 2008-12)
We show that local directional alignment of the velocity and magnetic field fluctuations occurs rapidly in magnetohydrodynamics for a variety of parameters and is seen both in direct numerical simulations and in solar wind ...
Statistics of magnetic reconnection in two-dimensional magnetohydrodynamic turbulence
(American Institute of Physics, 2010-03)
The nonlinear dynamics of magnetic reconnection in turbulence is investigated through direct numerical simulations of decaying, incompressible, two-dimensional magnetohydrodynamics. Recently, it was shown by Servidio [Phys. ...
THE ROLE OF TURBULENT MAGNETIC RECONNECTION IN THE FORMATION OF ROTATIONALLY SUPPORTED PROTOSTELLAR DISKS
(IOP PUBLISHING LTDBRISTOL, 2012)
The formation of protostellar disks out of molecular cloud cores is still not fully understood. Under ideal MHD conditions, the removal of angular momentum from the disk progenitor by the typically embedded magnetic field ...
Magnetic reconnection as an element of turbulence
(Copernicus Publications, 2011-10)
In this work, recent advances on the study of reconnection in turbulence are reviewed. Using direct numerical simulations of decaying incompressible two-dimensional magnetohydrodynamics (MHD), it was found that in fully ...
Statistical analysis of discontinuities in solar wind ace data and comparison with intermittent mhd turbulence
(IOP Publishing, 2009-12)
The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity ...
Instabilities; shocks and turbulence in space and astrophysical plasmas
(Asociación Argentina de Astronomía, 2018-10)
The dynamics of plasmas pervading the interplanetary and interstellar medium are often described within the frame of magnetohydrodynamics (MHD), which involves the coupling between flows and magnetic fields. This theoretical ...
