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. SOLAR WIND HEATING OBSERVED BY SOLAR ORBITER

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Karan Pal; [2023]
   Keywords : ;

   Abstract : In this project, we investigate the plasma heating associated with coherent structures, such as current sheets and vortices, in different solar wind conditions: slow solar wind, stream interaction regions, and heliospheric current sheets, observed by the Solar Or- biter mission. To unravel this mystery, we first use the Partial Variance of Increment method [1] to locate these coherent structures. READ MORE

5. 4. Cosmic Dust Detection by the Solar Orbiter Using Machine Learning

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Joar Lönngren; Ludwig Tiston; [2023]
   Keywords : Machine Learning; Neural Network; Cosmic Dust; Solar Orbiter; Space Physics; Space Dust;

   Abstract : This project aims to investigate neural network systems as an effective tool for the in-space captured dust impact signal detection. Cosmic dust is the nanometre to micrometre fine-sized particles that exist in the interplanetary region. They originate from comets, asteroids, the planets and their moons and rings, or even the interstellar region. READ MORE

6. 5. Improving the understanding of photoelectron currents on Solar Orbiter : Utilizing theory and empirical measurements

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Melker Marminge; [2023]
   Keywords : Solar Orbiter; Photoelectric Currents; Photoelectric Effect; Thermal Bending; Outgassing; Thermionic Emission; Numerical Approximation; Physical Modeling;

   Abstract : Spacecraft experience electric currents on conductive materials exposed to sunlight, which introduces noise in scientific data. These currents are mainly due to the photoelectric effect and should therefore be proportional to the inverse square heliocentric distance. READ MORE
