Abstract:

By assuming that coronal active regions are made up of many loops, we investigate the relationship between the average magnetic field strength and loop length for a sample of active regions observed by the Soft X-ray Telescope aboard Yohkoh. We use photospheric magnetic data from the Michelson Doppler Imager and compute extrapolated field lines that match the observed soft X-ray emission. We compare our results with a previous study and find them to be consistent and a logical extension of such work. Such studies have important implications for solar coronal heating models. © ESO 2006.
