Summary:
Ultimately, the magnetic energy in the Sun's atmosphere --- the source of dramatic eruptive events such as flares and coronal mass ejections --- is generated below the photosphere in the turbulent, differentially-rotating convective interior. The emergence of new magnetic flux into the solar atmosphere, the twisting and shearing of emerged magnetic flux by turbulent motions, and Alfven and magneto-acoustic waves from intermittent turbulent eddies are all viable mechanisms that can transport magnetic energy into the solar atmosphere. It is crucial that we understand these physical processes and be able to distinguish between them. Thus, we propose to develop and apply techniques to derive quantitative maps of the flux of electromagnetic energy into the solar atmosphere from below the visible surface. These techniques will be based on the recently-developed poloidal-toroidal decomposition (PTD) method of Fisher et al. (2010), and will use observations of the evolving vector magnetic field at the solar photosphere, and observed Doppler flows.Performance Year | Reference | Investigation Type | Actions |
