20.500.12556/RUL-173237 Dinamika Sončevih izbruhov koronalne mase magistrsko delo Dynamics of Solar coronal mass ejections V magistrskem delu je predstavljena analiza dinamike petih izbranih izbruhov koronalne mase (CMEs iz angl. »Coronal Mass Ejections«), ki sodijo med najmočnejše pojave Sončeve aktivnosti. Analiza temelji na javno dostopnih posnetkih, pridobljenih s koronografom LASCO C3 na satelitu SOHO. Z uporabo prosto dostopne programske opreme so na zaporednih posnetkih določeni položaji vodilnega roba izbruha ter izračunane projicirane razdalje, hitrosti in pospeški za pet izbranih dogodkov. Poleg tega se na podlagi enega reprezentativnega, obdelanega in kalibriranega posnetka za vsak dogodek preko Thomsonovega sipanja oceni masa izvržene plazme. Dobljeni rezultati dobro ponazarjajo dinamiko izbruhov in potrjujejo uporabnost predstavljenih metod za osnovno analizo tovrstnih pojavov. Metoda je zaradi dostopnosti programske opreme in jasne fizikalne podlage primerna za vključevanje v pouk fizike ali astronomije, zlasti v obliki raziskovalnega dela z nadarjenimi učenci. In this master’s thesis, an analysis of the dynamics of five selected coronal mass ejections (CMEs), which are among the most powerful manifestations of solar activity, is presented. The analysis is based on publicly available images obtained with the LASCO C3 coronagraph aboard the SOHO satellite. Using freely accessible software, the position of the leading edge of each eruption in sequential images was determined, and the projected distances, velocities, and accelerations for the five selected events were calculated. Additionally, based on one representative processed and calibrated image per event, the mass of the ejected plasma was estimated through Thomson scattering. The obtained results clearly illustrate the dynamics of the eruptions and confirm the effectiveness of the presented methods for the basic analysis of such phenomena. Due to the accessibility of the software and the clear physical foundations, the method is well-suited for integration into physics or astronomy education, particularly in the form of research projects with gifted students.
