Three-dimensional magnetic reconnection in a collapsing coronal loop system
Aidan M. O'Flannagain, Shane A. Maloney, Peter T. Gallagher +2
Magnetic reconnection is believed to be the primary mechanism by which non-potential energy stored in coronal magnetic fields is rapidly released during solar eruptive events. Unfo…
Global Energetics of Solar Flares: V. Energy Closure in Flares and Coronal Mass Ejections
Markus J. Aschwanden, Amir Caspi, Christina M. S. Cohen +11
In this study we synthesize the results of four previous studies on the global energetics of solar flares and associated coronal mass ejections (CMEs), which include magnetic, ther…
Global Energetics of Solar Flares: III. Non thermal Energies
Markus J. Aschwanden, Gordon Holman, Aidan O'Flannagain +3
This study entails the third part of a global flare energetics project, in which Ramaty High-Energy Solar Spectroscopic Imager (RHESSI) data of 191 M and X-class flare events from…
LOFAR tied-array imaging and spectroscopy of solar S bursts
D. E. Morosan, P. T. Gallagher, P. Zucca +50
Context. The Sun is an active source of radio emission that is often associated with energetic phenomena ranging from nanoflares to coronal mass ejections (CMEs). At low radio freq…
Solar Hard X-ray Source Sizes in a Beam-Heated and Ionised Chromosphere
A. O'Flannagain, J. C. Brown, P. T. Gallagher
Solar flare hard X-rays (HXRs) are produced as bremsstrahlung when an accelerated population of electrons interacts with the dense chromospheric plasma. HXR observations presented…
The Compatibility of Flare Temperatures Observed with AIA, GOES, and RHESSI
Daniel F. Ryan, Aidan M. O'Flannagain, Markus J. Aschwanden +1
We test the compatibility and biases of multi-thermal flare DEM (differential emission measure) peak temperatures determined with AIA with those determined by GOES and RHESSI using…
Solar Flare X-ray Source Motion as a Response to Electron Spectral Hardening
A. O'Flannagain, P. Gallagher, J. Brown +2
Context: Solar flare hard X-rays (HXRs) are thought to be produced by nonthermal coronal electrons stopping in the chromosphere, or remaining trapped in the corona. The collisional…
