Coronal loops: observations and modeling of confined plasma

F Reale - Living Reviews in Solar Physics, 2014 - Springer
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their
brightness to the dense confined plasma, and this review focuses on loops mostly as …

Patterns of nanoflare storm heating exhibited by an active region observed with Solar Dynamics Observatory/Atmospheric Imaging Assembly

NM Viall, JA Klimchuk - The Astrophysical Journal, 2011 - iopscience.iop.org
It is largely agreed that many coronal loops—those observed at a temperature of about 1 MK—
are bundles of unresolved strands that are heated by storms of impulsive nanoflares. The …

What dominates the coronal emission spectrum during the cycle of impulsive heating and cooling?

SJ Bradshaw, JA Klimchuk - The Astrophysical Journal …, 2011 - iopscience.iop.org
The" smoking gun" of small-scale, impulsive events heating the solar corona is expected to
be the presence of hot (> 5 MK) plasma. Evidence for this has been scarce, but has …
