3D Reconstruction of Active Regions with STEREO (Invited Review) View all abstracts by submitter

Markus J. Aschwanden   Submitted: 2010-02-24 16:33

We review data analysis and physical modeling related to the 3D reconstruction of active regions in the solar corona, using stereoscopic image pairs from the STEREO/EUVI instrument. This includes the 3D geometry of coronal loops (with measurements of the loop inclination plane, coplanarity, circularity, and hydrostaticity), the 3D electron density and temperature distribution (which enables diagnostics of hydrostatic, hydrodynamic, and heating processes), the 3D magnetic field (independent of any theoretical model based on photospheric extrapolations), as well as the 3D reconstruction of CME phenomena, such as EUV dimming, CME acceleration, CME bubble expansion, and associated Lorentz forces that excite MHD kink-mode oscillations in the surroundings of a CME launch site. The mass of CMEs, usually measured from white-light coronagraphs, can be determined independently from the EUV dimming in the CME source region. The full 3D density and temperature structure of an active region can be reconstructed in unprecedented detail with instant stereoscopic tomography.
