Center-to-Limb Variation of Radio Emissions from Thermal-Rich and Thermal-Poor Solar Flares
acceleration of particles—Sun: fl ares—Sun: magnetic fi elds—Sun:radio radiation—Sun: X-rays, gamma rays
2011/9/30
A statistical analysis of radio flare events was performed by using the event list of Nobeyama Radioheliograph in 1996-2009. We examined center-to-limb variations of 17GHz and 34GHz flux by dividing t...
Solar Flares and Coronal Mass Ejections: A Statistically Determined Flare Flux-CME Mass Correlation
Flares Coronal mass ejections
2010/11/9
In an effort to examine the relationship between flare flux and corresponding CME mass, we temporally and spatially correlate all X-ray flares and CMEs in the LASCO and GOES archives from 1996 to 2006...
Electrons re-acceleration at the footpoints of Solar Flares
Electrons re-acceleration footpoints of Solar Flares
2010/11/10
Hinode’s observations revealed a very dynamic and complex chro-mosphere. This require revisiting the assumption that the chromospheric foot-points of solar flares are areas where accelerated particles...
GEANT4 Simulations of Gamma-Ray Emission from Accelerated Particles in Solar Flares
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
Gamma-ray spectroscopy provides diagnostics of particle acceleration in solar flares, but care must be taken when interpreting the spectra due to effects of the angular distribution of the accelerated...
Electromagnetic (radio, visible-light, UV, EUV, X-ray and gamma-ray) emission generated by solar and stellar flares often contains pronounced quasi-periodic pulsations (QPP).
Evidence of Decay of Flux Ratio of Fe to Fe–Ni Line Features with Electron Temperature in Solar Flares
Sun flares corona—X-rays
2010/9/15
We report observational evidence of the decay of the flux ratio of Fe to Fe–Ni line features as a function of plasma electron temperature in solar flares in comparison to that theoretically predicted ...
