| Abstract: |
The decay of flare X-ray light curves provides information on the dimensions of the flaring region. We show that a reliable estimate of such dimensions must take into account the temperature evolution as tracer of the presence of heating during the decay. Many solar flares appear sustained by prolonged heating episodes. We describe a method to estimate their spatial extension based on the analysis of the decay of their X-ray light curve and temperature, and show that the results are in good agreement with their dimensions measured on Yohkoh/SXT images. |
