Prominence and flare fine structure from cross-field thermal conduction

  title={Prominence and flare fine structure from cross-field thermal conduction},
  author={Norman Gray and John C. Brown},
  journal={arXiv: Astrophysics},
Thermal conduction across a magnetic field is strongly suppressed compared with conduction along the field. However, if a flare is heated by a highly filamented beam directed along the field, then the array of heated cells in a cross-section of the flare will result in both small spatial scales (with consequently large temperature gradients) and a large surface area for the heated volume, providing a geometrical enhancement of the total cross-field energy flux. To investigate the importance of… Expand

I stated my belief that the spots were produced by the downward rush of, comparatively speaking, cool portions of gas which had been in the first instance ejected during these eruptions, and found that Mr. Lockyer had obtained independent evidence from his spectroscopic researches that these spots consisted of down-rushes of gas, and not, as some have supposed, of up-rusches.
