Title:

X-ray Spectra from Hinotori Satellite and Suprathermal Electrons

Date of publication:

Oct. 1992

Key words:

solar flares, X-ray spectrum, He-like and H-like iron ions, suprathermal electrons

Abstract:

We analyzed the X-ray spectra of H-like and He-1ike iron ions from a solar flare observed by Hinotori satellite, taking into account of a possible contribution of high energy electrons. The time behaviour of the relative densities of iron ions was calculated for a plasma of non- equilibrium ionization in the presence of suprathermal electrons of a few percent fraction. This model can reproduce the time evolution of the H-like and He-like spectra consistently.
