Journal ArticleDOI
Emergence of a twisted magnetic flux bundle as a source of strong flare activity
TL;DR: Sunspot proper motions and flares of a super active region NOAA 5395 were analyzed in detail by using the Hα -5.0 A images obtained with the 60 cm Domeless Solar Telescope (DST) at Hida Observatory, Kyoto University as discussed by the authors.

TL;DR: In this paper, a compilation of data for all 258 gamma-ray bursts detected above 300 keV by the Gamma Ray Spectrometer (GRS) aboard the Solar Maximum Mission satellite is presented.

X-ray spectroscopy of stellar coronae
TL;DR: In this paper, the spectral properties of the X-ray emitting corona of stars on the cool side of the Hertzsprung-Russell diagram have been investigated using the spectrometers of NASA'sAXAF and ESA'sXMM.
Journal ArticleDOI
Electron-cyclotron maser observable modes
TL;DR: In this paper, a model for the saturation length and amplification ratio of the electron-cyclotron maser was developed to calculate the absorption and emission coefficients for every frequency and angle.

Simulation of charge-equilibration and acceleration of solar energetic ions
A. F. Barghouty,R. A. Mewaldt +1 more
TL;DR: In this paper, a nonequilibrium model for the mean ionic charge that includes shock-induced acceleration in addition to charge-changing processes was proposed, which is able to reproduce the general features observed without specifying uniquely the acceleration time and the plasma electron density.
