Ion Cyclotron Damping in the Solar Corona and Solar Wind
The solar corona is the hot, ionized outer atmosphere of the Sun. Coronal plasma expands into interplanetary space as a supersonic bulk outflow known as the solar wind. This tenuous and unbounded medium is a unique laboratory for the study of kinetic theory in a nearly collisionless plasma, as well as magnetohydrodynamic waves, shocks, and jets. Particle velocity distributions in the solar wind...
متن کاملComposition Variations in the Solar Corona and Solar Wind
Order of magnitude variations in relative elemental abundances are observed in the solar corona and solar wind. The instruments aboard SOHO make it possible to explore these variations in detail to determine whether they arise near the solar surface or higher in the corona. A substantial enhancement of low First Ionization Potential (FIP) elements relative to high FIP elements is often seen in ...
متن کاملObserved Associations between the Solar Interior, Corona, and Solar Wind
Using polarized brightness (pB) measurements made by the High Altitude Observatory (HAO) Mauna Loa Mk III K-coronameter, we investigate the daily changes of path-integrated density at 1.15 R,. During 1996, when simultaneous pB and helioseismology data were available, we find that the correlation of pB (at zero time lag and 207 latitude lag) varies with latitude in the same way that the subsurfa...
متن کاملMhd-driven Kinetic Dissipation in the Solar Wind and Corona
Mechanisms for the deposition of heat in the lower coronal plasma are discussed, emphasizing recent attempts to reconcile the Ñuid and kinetic perspectives. Structures at magnetohydrodynamic (MHD) scales may drive a nonlinear cascade, preferentially exciting high perpendicular wavenumber Ñuctuations. Relevant dissipative kinetic processes must be identiÐed that can absorb the associated energy ...
متن کاملPrimary Flows, the Solar Wind and the Corona
Based on the conjectured existence of primary solar emanations (plasma flows from the solar surface), a model for the Origin of the Fast Solar Wind, and the creation and heating of the coronal structures is developed. Preliminary results reproduce many of the salient observational features.
