Electron Temperature of Solar Flares Derived from Helium-Like Sulphur Lines
Abstract
The maximum temperatures and emission measures reached in solar flares were obtained from helium-like sulphur lines, which were observed by the Bragg Crystal Spectrometer on board Yohkoh. A very weak dependence of the maximum temperature against the soft X-ray intensity was found. Similar multi-thermal characteristics prevailed in flares irrespective of the flare intensity, suggesting that the solar flare is a homogeneous phenomenon in the solar atmospheres.
