Constraining the Mass Loss and the Kinetic Energy of Stellar Coronal Mass Ejections with Solar Far-ultraviolet Flares

The Astrophysical Journal
Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres.

HARD X-RAY IMAGING OF SOLAR FLARES USING INTERPOLATED VISIBILITIES

The Astrophysical Journal, 2009
RHESSI produces solar flare images with the finest angular and spectral resolutions ever achieved at hard X-ray energies. Because this instrument uses indirect, collimator-based imaging techniques, the "native" output of which is in the form of "visibilities" (two-dimensional spatial Fourier components of the image), the development and application of ...

Results from the solar maximum mission [PDF]

The major results from SMM (Solar Max Mission) are presented as they relate to the understanding of the energy release and particle transportation processes that led to the high energy X-ray aspects of solar flares. Evidence is reviewed for a 152- to 158-

A Statistical Study of Gamma-Ray Emitting Solar Flares Observed with Yohkoh

, 2005
Gamma-ray emitting solar flares observed with Yohkoh were analyzed from a statistical viewpoint. The four-band hard X-ray (15--95 keV) photometric data, taken with the Hard X-ray Telescope onboard Yohkoh, were utilized in combination with the spectro ...

Implications for electron acceleration and transport from non-thermal electron rates at looptop and footpoint sources in solar flares [PDF]

, 2013
The interrelation of hard X-ray (HXR) emitting sources and the underlying physics of electron acceleration and transport presents one of the major questions in the high energy solar flare physics.

Height and Energy Evolution of X-Ray Double Sources in a Solar Flare

The Astrophysical Journal
In the standard model, magnetic reconnection at a vertical current sheet above the flare arcade is key to explaining many aspects of solar eruptions. The supra-arcade region is where the vertical current sheet is supposedly located, and X-ray/extreme ...
