Numerical Simulation of a Solar Active Region. I: Bastille Day Flare
Charbonneau, Paul; Vincent, Alain; Dubé, Caroline
We present three-dimensional unsteady modeling and numerical simulations of a coronal active region, carried out within the compressible single-fluid MHD approximation. We focus on AR 9077 on 14 July 2000, and the triggering of the X5.7 GOES X-ray class "Bastille Day" flare. We simulate only the lower corona, although we include a virtual photosph…
Outflow Velocity Structure in the Upper Transition Region and Corona
Abbo, Lucia; Gabriel, Alan
Outflow velocity maps in the quiet Sun and coronal hole regions have been observed with the EUV Imaging Spectrometer on Hinode over a range of coronal and transition region temperatures, in order to correlate the solar wind with effects due to the underlying supergranule network and to coronal holes. The cell structure has been identified using da…
