Heliosphere

The Wigner Space team studies the Sun and the heliosphere focusing on their plasma processes and their effects on the planetary, cometary or spacecraft plasma environments.

The solar wind propagation throughout the inner heliosphere is studied by a multi-spacecraft and multi-model approach financed by OTKA grant FK128548 and lead by Andrea Opitz. We improve our methods through detailed study of CIRs (Gergely Kobán). Our propagation tools were extended to 3D and we have nice visualizations now (Anikó Timár).

Considering the Solar Orbiter mission (2020-) our team is Co-Investigator in the SolO MAG magnetometer. Currently, we study directional discontinuities (Ákos Madár) and solar wind radial propagation (Nikolett Biró).

Previous research of our team includes the magnetic flux in the solar wind (Géza Erdős) from Ulysses observations, and the solar wind structures from STEREO measurements (Opitz et al. 2009), Venus Express and Messenger observations (Dosa and Erdos 2017).

The outer heliosphere is intensively studied by the Voyager 1 and 2 spacecraft that have passed the heliopause in 2012 and 2018, respectively.
