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 ...

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 ...
Early-type galaxies at z 1.3. III. on the dependence of formation epochs and star formation histories on stellar mass and environment
(2011)
We study the environmental dependence of stellar population properties at z ~ 1.3. We derive galaxy properties (stellar masses, ages and star formation histories) for samples of massive, red, passive early-type galaxies ...
Steady-state sphere-like and ring-like formations of the free electromagnetic field in vacuum
(Sociedad italiana de Física, 2002-12-15)
It is shown that there are exact solutions of the free Maxwell equations in vacuum allowing and existence of closed spherical magnetic surfaces (without electric field on this surface and where magnetic field is tangential ...
Spatially resolved magnetic field structure in the disk of a T Tauri star
(Nature Publishing Group, 2014-10)
Magnetic fields in accretion disks play a dominant role during the star formation process but have hitherto been observationally poorly constrained. Field strengths have been inferred on T Tauri stars themselves and possibly ...
Conditions for jet formation in accreting neutron stars: the magnetic field decay
(Cambridge University Press, 2011)
Accreting neutron stars can produce jets only if they are weakly magnetized (B~10^8 G). On the other hand, neutron stars are compact objects born with strong surface magnetic fields (B~10^12 G). In this work we study the ...
Local star formation triggered by supernova shocks in magnetized diffuse neutral clouds
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
In this work, considering the impact of a supernova remnant (SNR) with a neutral magnetized cloud we derived analytically a set of conditions that are favourable for driving gravitational instability in the cloud and thus ...
La formación de formadores : un campo a descubrir desde el propio trayecto profesionalThe formers formation : a field to be discovered from its professional section
(Universidad Nacional del Nordeste. Facultad de Humanidades, 2015-06-30)
Al incursionar -desde mediados de la década del 90- en el campo de la formación de formadores, surgió la necesidad de clarificar nuestro posicionamiento epistemológico para su abordaje, lo cual significó una toma en ...
Unusual formations of the free electromagnetic field in vacuum
(Institute of Physics Publishing, 2002-09)
It is shown that there are exact solutions of the free Maxwell equations (FME)
in vacuum allowing the existence of stable spherical formations of the free
magnetic field and ring-like formations of the free electric ...
