1. 1. Study of oblique whistler waves in coronal mass ejections observed by Solar Orbiter

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Sofia Lennerstrand; [2023]
   Keywords : Oblique whistler waves; Solar physics; Solar Orbiter;

   Abstract : 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. READ MORE

3. 2. WSA-ENLIL + Cone ensemble modeling of an Earth-directed ICME : Comparison with in-situ observations by Solar Orbiter and WIND at L1

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Alberto García Ribas; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

4. 3. Drag based forecast for CME arrival

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Simon Jaklovsky; [2020]
   Keywords : CME; ICME; Halo coronal mass ejections; DBM; DBEM; solar wind; interplanetary medium; shock; space weather forecast; geoeffectivity; solar-terrestrial interaction;

   Abstract :           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. READ MORE

5. 4. Reconstructing ICMEs with the toroidal Grad-Shafranov method

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Moa Skan; [2019]
   Keywords : space physics; plasma; coronal mass ejections; interplanetary coronal mass ejections;

   Abstract : 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. READ MORE

6. 5. Comparison of the shock arrival times for Earth-directed ICMEs provided by the WSA-Enlil+Cone model and in-situ observations at L1: A Case Study

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Anita Linnéa Elisabeth Werner; [2016]
   Keywords : CME; ICME; CIR; WSA-Enlil Cone; CCMC; ACE; SAT; St. Patrick; Sun-Earth connection;

   Abstract : A case study which examines the agreement between prediction and data is performed for three, complex interplanetary shocks which were detected at the Sun-Earth Lagrange point L1 and induced moderate to intense geomagnetic storms. We use model output from previous runs of the coupled coronal-heliosphere WSA-Enlil+Cone model, available through the Community Coordinated Modeling Center (CCMC), and in-situ data from the OMNI data set.
