| Description
| - Vysokoenergetické elektrony jsou studovány v prostorovém a časovém vývoji v několika spektrálních oborech (RHESSI,H?, rádio, TRACE, MDI) pro případ erupce z 20. srpna 2002, která vykazovala neobvykle ploché rentg. spektrum. Pro odvození primárního rentg. spektra byla použita nová metoda zahrnující vliv Comptonovského rozptylu rentg. fotonů ve fotosféře (fotosférické albedo). Je ukázáno, že příspěvek fotosférického albeda k fotonovému spektru modifikuje odvozenou střední distribuční funkci elektronů. Rádiová emise a pozice zdrojů v H? a rentg. emisi vzhledem k bezproudové extrapolaci fotosférického magnetického pole podávají důkaz o uzavřené geometrii magnetického pole a erupčním procesu v nízkých magnetických smyčkách. Rentg. zdroje se nacházejí na vnějsích okrajích H? emise a ukazují chromosférickou plazmu ohřátou vysokoenergetickými elektrony. Rychlé změny H? emise jsou nalezeny jak uvnitř rentg. zdrojů, tak i mimo ně. (cs)
- A multi-wavelength (RHESSI, H?, radio, TRACE, MDI) spatial and temporal analysis of solar high-energy electrons is conducted using the August 20, 2002 flare of an unusually flat hard X-ray spectrum. A new method to account for X-ray Compton backscattering in the photosphere (photospheric albedo) has been used to deduce the primary X-ray flare spectra. We show that the contribution of the photospheric albedo to the photon spectrum modifies the calculated mean electron flux distribution. The radio emission and the positions of the H? and hard X-ray sources with respect to the current-free extrapolation of the photospheric magnetic field provide evidence of the closed geometry of the magnetic field and the flare process in low altitude magnetic loops. The hard X-ray sources are located on the external edges of the H? emission and show chromospheric plasma heated by the high-energy electrons. The fast changes of H? emission are found inside the hard X-ray sources as well as away from them.
