Configuración magnética pre-eruptiva de la región NOAA 12127 mediante extrapolación no lineal del campo
(Asociación Argentina de Astronomía, 2021)
Estudiamos las propiedades magnéticas de la región activa NOAA 12127 previas a una fulguración clase M1.5, acompañada de una eyección coronal de masa, el 1 de agosto de 2014. Estimamos su campo magnético coronal preeruptivo ...

Turbulent magnetic pumping in a Babcock-Leighton solar dynamo model
(EDP SCIENCES S A, 2008)
Context. The turbulent pumping effect corresponds to the transport of magnetic flux due to the presence of density and turbulence gradients in convectively unstable layers. In the induction equation it appears as an advective ...

Outflows at the edges of active regions: Contribution to solar wind formation?
(IOP Publishing, 2008-12)
The formation of the slow solar wind has been debated for many years. In this Letter we show evidence of persistent outflow at the edges of an active region as measured by the EUV Imaging Spectrometer on board Hinode. The ...

Evolution of spinning and braiding helicity fluxes in solar active region NOAA 10930
(IOP Publishing, 2011-12)
The line-of-sight magnetograms from Solar Optical Telescope Narrowband Filter Imager observations of NOAA Active Region 10930 have been used to study the evolution of spinning and braiding helicities over a period of five ...

SURFACE ALFVEN WAVE DAMPING IN A THREE-DIMENSIONAL SIMULATION OF THE SOLAR WIND
(IOP PUBLISHING LTD, 2009)
Here we investigate the contribution of surface Alfven wave damping to the heating of the solar wind in minima conditions. These waves are present in the regions of strong inhomogeneities in density or magnetic field (e.g., ...
