Multi-spacecraft observations of shocklets at an interplanetary shock

Vainio, R.; Horbury, T.; Dresing, N. +5 more

Interplanetary (IP) shocks are fundamental building blocks of the heliosphere, and the possibility to observe them in situ is crucial to address important aspects of energy conversion for a variety of astrophysical systems. Steepened waves known as shocklets are known to be important structures of planetary bow shocks, but they are very rarely obs…

Self-consistent nanoflare heating in model active regions: MHD avalanches

Hood, A. W.; Threlfall, J.; Reid, J.

Straightened cylindrical models of coronal loops have been standard for decades, and shown to support nanoflare-like heating, but the influence of geometric curvature in models upon the heating produced has not been discussed in depth. Heating, its spatiotemporal distributions, and the associated mechanisms responsible are discussed, and compared …
