1. Study of oblique whistler waves in coronal mass ejections observed by Solar Orbiter
Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : In this paper a search routine in MATLAB was developed in order to find and analyze oblique whistler waves in the data from the ESA and NASA spacecraft Solar Orbiter. Oblique whistler waves are a type of plasma wave which propagate at an angle with respect to the background magnetic field. LÄS MER
2. WSA-ENLIL + Cone ensemble modeling of an Earth-directed ICME : Comparison with in-situ observations by Solar Orbiter and WIND at L1
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : Coronal mass ejections (CMEs) are considered the most energetic phenomenon in the heliosphere. Originated in the solar corona, they are formed by ejected plasma driven by strong magnetic fields. LÄS MER
3. Drag based forecast for CME arrival
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Coronal Mass Ejections (CMEs) are considered to be one of the most energetic events in the heliosphere. Capable of inducing geomagnetic storms on Earth that can cause damage to electronics, a pillar which the modern society we live in leans heavily upon. LÄS MER
4. Interpreting density enhancement of coronal mass ejections
Kandidat-uppsats, Uppsala universitet/Rymd- och plasmafysikSammanfattning : Coronal mass ejections (CMEs) are some of the extraterrestrialevents most impactful to earth. Eorts to model and predict theireects have seen new possibilities in the two most recent decades dueto multiple new spacecrafts providing a wider range of data than everbefore. LÄS MER
5. Reconstructing ICMEs with the toroidal Grad-Shafranov method
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : The main objective of this thesis is to model the magneticstructure of interplanetary coronal mass ejections (ICME) measuredin-situ from the WIND spacecraft positioned at L1. The modeling isdone by a magnetohydrodynamic reconstruction technique based onthe GS equation with a toroidal geometry. LÄS MER
