The Power-Law Distribution of Flare Kernels and Fractal Current Sheets in a Solar Flare

N. Nishizuka, A. Asai, H. Takasaki +2

We report a detailed examination of the fine structure inside flare ribbons and the temporal evolution of this fine structure during the X2.5 solar flare that occurred on 2004 Nove…

Multiple Plasmoid Ejections and Associated Hard X-ray Bursts in the 2000 November 24 Flare

N. Nishizuka, H. Takasaki, A. Asai +1

The Soft X-ray Telescope (SXT) on board Yohkoh revealed that the ejection of X-ray emitting plasmoid is sometimes observed in a solar flare. It was found that the ejected plasmoid…

Temporal and Spatial Analyses of Spectral Indices of Nonthermal Emissions Derived from Hard X-Rays and Microwaves

Ayumi Asai, Junko Kiyohara, Hiroyuki Takasaki +5

We studied electron spectral indices of nonthermal emissions seen in hard X-rays (HXRs) and in microwaves. We analyzed 12 flares observed by the Hard X-ray Telescope aboard {\it Yo…

Numerical examination of plasmoid-induced reconnection model for solar flares: the relation between plasmoid velocity and reconnection rate

Keisuke Nishida, Masaki Shimizu, Daikou Shiota +3

The plasmoid-induced-reconnection model explaining solar flares based on bursty reconnection produced by an ejecting plasmoid suggests a possible relation between the ejection velo…

Measurement of the Energy Release Rate and the Reconnection Rate in Solar Flares

Hiroaki Isobe, Hiroyuki Takasaki, Kazunari Shibata

By using the method presented by Isobe et al. (2002), the non-dimensional reconnection rate Vin/Va has been determined for the impulsive phase of three two-ribbon flares, where Vin…
