Title:Propagation of interplanetary shocks in the heliosphere
Topic:NASA and the European Space Agency dispatched a fleet to study the heliosphere and the planets of the Solar System. A few probes were measured inside the orbit of the Earth, some missions collected data outside of the orbit of the our planet. In the meantime, another group of space probes recorded the variations ofthe solar wind at the L1 Lagrange point. The purpose of this thesis is the observation of interplanetary shocks by at least two different spacecraft. Furthermore, to determine the changes and developements of the shock parameters during propagation. Finally, the collected conjigated observations should be compared with exixting models and simulations.

Title:Temporal Development of Interplanetary Shocks in the Heliosphere
Topic:Interplanetary shocks are one of the crucial dynamic processes in the Heliosphere. They accelerate particles into high energy, generate plasma waves and could potentially trigger geomagnetic storms in the terrestrial magnetosphere disturbing significantly our technological infrastructures. In this study, two IP shock events are selected to investigate the temporal variations of the shock parameters using magnetometer and ion plasma measurements of the STEREO A and B, the Wind, and the ACE spacecraft. The shock normal vectors are determined using the minimum variance analysis (MVA) and the magnetic coplanarity methods. During the May 07 event, the shock parameters and the shock normal direction are consistent. During the April 23 event, the shock parameters do not change significantly, however, the shape of the IP shock appears to be twisted along the transverse direction to the Sun-Earth line. Stereo B does not observe the IP shock signatures during this event.

PhD and MSc thesis topics

  1. Test of the Boundary Layer Identification Code

    I developed a code in Matlab to find the bow shock crossings in the measurements of the Cluster fleet. The task is to test its prediction capabilities.

  2. Study of interaction of the magnetospheres of giant planets

    Ilja Honkonen (FMI) made an MHD simulation when the Kronian magnetosphere enters the Jovian magnetosphere. The task is to compare the simulation results with in-situ Cassini measurements at Saturn.

  3. Full particle simulation of the solar wind-Moon surface interaction

    The Moon spends 25% of its orbit in the magnetosphere of the Earth and it changes the interactions of the solar wind with the lunar surface. Andrey Divin (IRF, Sweden) made a full particle simulation of the Moon-solar wind interaction. The task is to finish the analysis of the results.

  4. Turbulence in the cavity of Hot Flow Anomalies

    The Magnetospheric Multiscale (MMS) Mission has an incredible temporal resolution. The task is to check some dayside transient events and study the turbulence and shocks around and within them.

  5. Study of the bow shock in the far tail

    The terrestrial bow shock was observed at 2000 RE by interplanetary missions. Using Wind, THEMIS/ARTEMIS, and STEREO measurements you should study the bow shock in the far tail.
