Abstract
When coronal mass ejections (CMEs) propagate through interplanetary space, they interact with the surrounding magnetic field and solar wind, which are neither homogeneous nor isotropic. Consequently, CMEs with different orientations may face varying environmental conditions, leading to different interactions based on their orientation. Our observational studies include remote and in-situ analysis of CMEs. We derived their orientation near Sun using 3D and 2D CME geometry reconstruction methods... More based on remote observations, as well as their orientation near Earth using a rotational profile of the magnetic field detected in-situ. A complementary simulation study was performed using the EUropean Heliospheric FORecasting Information Asset, a 3D magnetohydrodynamic (MHD) model with two spheromak CMEs, differing only in inclination. In general, we found that plasma flows in front of the CME differ based on orientation, though no significant difference in MHD drag between different orientations was found. These findings enhance our understanding of CME-ambient interactions, which is crucial for advancing space weather predictions. Less
Abstract (croatian)
Koronini izbačaji (engl., coronal mass ejections, CMEs) u međuplanetarnom prostoru međudjeluju s okolnim magnetskim poljem i Sunčevim vjetrom, koji ne pokazuju homogenost niti izotropnost. Posljedično, CME-ovi različitih orijentacija nailaze na drugačije uvijete u međuplanetarnom prostoru, stoga njihovo međudjelovanje može ovisiti o orijentaciji CME-ova. Proučavali smo CME-ove različitih orijentacija pomoću daljinskih i in-situ podataka. Orijentacija CME-ova blizu Sunca određena je koristeći... More metode 3D i 2D rekonstrukcije geometrije iz daljinskih mjerenja. Orijentacija CME-a u blizini Zemlje određena je koristeći rotacijski profil magnetskog polja mjerenog insitu. Komplementarna analiza je provedena pomoću EUropean Heliospheric FORecasting Information Asset, 3D magnetohidrodinamiˇckog (MHD) modela, sa sferomak reprezentacijom dva CME-a koji se razlikuju jedino po orijentaciji. Pokazali smo da tok plazme, neposredno ispred CME-ova, ovisi o orijentaciji istih, međutim značajna razlika u MHD otporu nije pronađena. Ovaj rad doprinosi boljem razumijevanje interakcije između CME-ova i ambijentalog magnetskog polja te Sunčevog vjetra, što je ključno za poboljšanje predikcija u okviru svemirskog vremena (engl. space weather).
