| Abstract | Movimentos horizontais e verticais do plasma na fotosfera têm um papel importante na formação de correntes elétricas na atmosfera do Sol. Essas correntes podem ser dissipadas e aquecer a coroa solar, gerar pequenas explosões solares (bright points) vistas em extremo ultravioleta ou em raios X ou desencadear grandes explosões solares (solar flares). Neste trabalho estudam-se os efeitos de diferentes tipos de movimentos horizontais na fotosfera do Sol na formação de correntes elétricas na atmosfera solar e a localização dessas correntes. Para realizar esse estudo utilizou-se um modelo magnetohidrodinâmico em três dimensões. O modelo resolve um conjunto apropriado de equações magnetohidrodinâmicas e usa o campo magnetico extrapolado a partir do campo magnetico de linha de visada, medido pelo Michelson Doppler Imager (MDI/SOHO) abordo do sat´elite Solar and Heliospheric Observatory (SOHO), como condição inicial do modelo. Os diferentes tipos de movimento horizontal presentes na fotosfera são determinados a partir da evolução temporal das estruturas magnéticas presentes nas medidas do campo magnético fotosférico. Esses movimentos são inseridos na condição de contorno aplicada na base do volume de simulação. ABSTRACT: Horizontal and vertical motions of the plasma in the solar photosphere have an important role in the build-up of electric currents in the solar atmosphere. These electric currents could dissipate and heat the corona, generate Extreme-Ultraviolet and X-ray Bright Points or trigger flares. We study the effects of different types of horizontal photospheric plasma motion for the generation of electric currents in the solar atmosphere and the location of these currents. To perform this study we use a data driven three dimensional magnetohydrodynamic model. The model solves an appropriate set of magnetohydrodynamic equations and uses the magnetic field extrapolated from the line-of-sight component of the photospheric magnetic field, observed by the Michelson Doppler Imager (MDI/SOHO), as initial condition. The different types of horizontal photospheric plasma motion, derived from the temporal evolution of the magnetic structures in the photospheric line-of-sight magnetograms, are used as boundary condition of the model. | |||
