The dynamics of unforced turbulence at high reynolds number for taylor-green vortices generalized to mhd
(Taylor & Francis Ltd, 2010-04)
We study decaying magnetohydrodynamics (MHD) turbulence stemming from the evolution of the Taylor-Green flow generalized recently to MHD, with equal viscosity and magnetic resistivity and up to equivalent grid resolutions ...
The role of reconnection diffusion in the gravitational collapse of turbulent cloud cores
(International Astronomical UnionFlorianópolis, 2013)
For a molecular cloud clump to form stars some
transport of magnetic flux is required from the
denser, inner regions to the outer regions of the
cloud, otherwise this can prevent the collapse. Fast
magnetic reconnection ...
A data-driven, two-temperature solar model with Alfven waves
(IOP Publishing, 2010-12-10)
We have developed a new three-dimensional magnetohydrodynamic (MHD) solar wind model coupled to the Space Weather Modeling Framework (SWMF), that solves for the different electron and proton temperatures. The collisions ...
Increase of ionization fraction of dusty proto-stelLar accretion disks by damping of Alfvén waves
(International Astronomical UnionFlorianópolis, 2013)
The ambient of the cloud that gives rise to the process
of star formationconsisted of: turbulence, magnetic
field and dust. In general, in the process of
star formation there is the formation of an accretion
disk whose ...
Instability of magnetic equilibria in barotropic stars
(Oxford University Press, 2015)
In stably stratified stars, numerical magnetohydrodynamics simulations have shown that arbitrary
initial magnetic fields evolve into stable equilibrium configurations, usually containing
nearly axisymmetric, linked ...
Inestabilidades paramétricas de una onda de alfvén circularmente polarizada en un plasma de varias especies iónicas: efectos cinéticos.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Física., 2007)
Se quiere investigar las inestabilidades paramétricas de una onda de Alfv¶en circularmente polarizada que se propaga en un plasma de electrones protones y partículas alfa a lo largo de un campo magnético de fondo. El interés ...
Magnetic field components analysis of the SCUPOL 850μm polarization data catalog
(Chicago, 2013)
We present an extensive analysis of the 850 μm polarization maps of the SCUBA Polarimeter Legacy (SCUPOL) Catalogue produced by Matthews et al., focusing exclusively on the molecular clouds and star-forming regions. For ...
Structured ionospheric outflow during the Cassini T55–T59 Titan flybys
(Elsevier, 2011-06)
During the final three of the five consecutive and similar Cassini Titan flybys T55–T59 we observe a region characterized by high plasma densities (electron densities of 1–8 cm3 ) in the tail/nightside of Titan. This region ...
Evolution of the Global Temperature Structure of the Solar Corona During the Minimum between Solar Cycles 23 and 24
(Iop Publishing Ltd, 2013-07-19)
The combination of Differential Emission Measure Tomography (DEMT) with extrapolation of the photospheric magnetic field allows determinatio/n of the electron density and electron temperature along individual magnetic field ...
