Title: | Evolution of Flaring Structures | |
Authors: | B. Sylwester and J. Sylwester | |
Abstract: | We present results of the study
aimed to analyse the morphology of evolving coronal X-ray
flaring structures. Our analysis deals with the Yohkoh
SXT observations obtained during flares. In order to
remove the telescope PSF blurring and improve the spatial
resolution on the images we incorporated the ANDRIL
maximum likelihood deconvolution algorithm. Using
deconvolved images, we determined the distribution of
physical conditions (Temperature-T, Emission
Measure-EM) as they change with time for several
flares. The results obtained indicate that the ''magnetic
connectivity'' pattern is vividly changing as flare
progress. We put forward new ''hierarchical'' model of the coronal magnetic field organisation in order to explain the observed evolution of flaring structures. |
