Modeling coronal energy storage and release in
نویسنده
چکیده
The X-ray corona is richly structured with individual plasma loops. A model is presented explaining these loops as the sites of magnetic energy storage and sporadic release. Energy is stored as coronal currents driven inductively by motions at the photosphere. These currents occur at internal boundaries in the coronal eld called separator. A method is described for completely characterizing the topology of any complex model eld, and thereby locating its separators. Magnetic reconnection provides the only mechanism for relieving coronal stresses. Assuming such relief does occur the model predicts the locations and energy of coronal activity.

Implosions in Coronal Transients.
Coronal events such as flares or coronal mass ejections derive their energy from the energy stored locally in the magnetic field. This leads to the conjecture that a magnetic implosion must occur simultaneously with the energy release. The site of the implosion would show the location of preflare energy storage, and its detection should have a high priority. The Transition Region and Coronal Ex...

متن کاملMagnetic Reconnection for Coronal Conditions: Reconnection Rates, Secondary Islands and Onset
Magnetic reconnection may play an important role in heating the corona through a release of magnetic energy. An understanding of how reconnection proceeds can contribute to explaining the observed behavior. Here, recent theoretical work on magnetic reconnection for coronal conditions is reviewed. Topics include the rate that collisionless (Hall) reconnection proceeds, the conditions under which...
