    Large-scale Coronal Heating, Clustering of Coronal Bright Points, and Concentration of Magnetic Flux (1999)
    Springer
    Space science reviews 87 (1999), S. 181-184

    Topics: Physics
    Notes: Abstract By combining quiet-region Fe XII coronal images from SOHO/EIT with magnetograms from NSO/Kitt Peak and from SOHO/MDI, we show that the population of network coronal bright points and the magnetic flux content of the network are both markedly greater under the bright half of the large-scale quiet corona than under the dim half. These results (1) support the view that the heating of the entire corona in quiet regions and coronal holes is driven by fine-scale magnetic activity (microflares, explosive events, spicules) seated low in the magnetic network, and (2) suggest that this large-scale modulation of the magnetic flux and coronal heating is a signature of giant convection cells.

    Coronal Heating by Magnetic Explosions (1999)
    Springer
    Space science reviews 87 (1999), S. 283-286 
    Details
    ISSN: 1572-9672
    Keywords: coronal heating ; magnetic field ; magnetic shear ; magnetic explosion
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract From magnetic fields and coronal heating observed in flares, active regions, quiet regions, and coronal holes, we propose that exploding sheared core magnetic fields are the drivers of most of the dynamics and heating of the solar atmosphere, ranging from the largest and most powerful coronal mass ejections and flares, to the vigorous microflaring and coronal heating in active regions, to a multitude of fine-scale explosive events in the magnetic network, driving microflares, spicules, global coronal heating, and, consequently, the solar wind.
