Can Large Time Delays Observed in Light Curves of Coronal Loops be Explained by Impulsive Heating?

Roberto Lionello, Caroline E. Alexander, Amy R. Winebarger +2

The light curves of solar coronal loops often peak first in channels associated with higher temperatures and then in those associated with lower. The time delays between the differ…

Trigger Mechanism of Solar Subflares in a Braided Coronal Magnetic Structure

Sanjiv K. Tiwari, Caroline E. Alexander, Amy R. Winebarger +1

Fine-scale braiding of coronal magnetic loops by continuous footpoint motions may power coronal heating via nanoflares, which are spontaneous fine-scale bursts of internal reconnec…

Sparkling EUV bright dots observed with Hi-C

S. Regnier, C. E. Alexander, R. W. Walsh +12

Observing the Sun at high time and spatial scales is a step towards understanding the finest and fundamental scales of heating events in the solar corona. The Hi-C instrument has p…
