3D pressure-corrected ballistic extrapolation of solar wind speed in the inner heliosphere

Autor: Timar Aniko, Opitz Andrea, Nemeth Zoltan, Bebesi Zsofia, Biro Nikolett, Facskó Gábor, Koban Gergely, Madar Akos

Publikováno v: Journal of Space Weather and Space Climate, Vol 14, p 14 (2024)

Solar wind parameters at different locations in the inner heliosphere can be estimated using various solar wind extrapolation methods. The simple ballistic method extrapolates solar wind parameters from the point of measurement to a chosen heliospher

Propagation of Interplanetary Shocks in the Heliosphere

Autor: Lkhagvadorj, Munkhjargal, Facsko, Gabor, Opitz, Andrea, Kovacs, Peter, Sibeck, David G.

Interplanetary shocks are one of the crucial dynamic phenomena in the Heliosphere. They accelerate particles to high energies, generate plasma waves, and can trigger geomagnetic storms in the terrestrial magnetosphere disturbing significantly our tec

Orientation of the stream interface in CIRs

Autor: Koban Gergely, Opitz Andrea, Biro Nikolett, Nemeth Zoltan

Publikováno v: Journal of Space Weather and Space Climate, Vol 13, p 14 (2023)

Corotating Interaction Regions (CIRs) are complex structures in the Heliosphere that arise from the interaction of fast and slow solar wind streams. The interface between fast and slow solar wind is called the stream interface, which often has consid

Estimating the solar wind pressure at comet 67P from Rosetta magnetic field measurements

Autor: Timar Aniko, Nemeth Zoltan, Szego Karoly, Dósa Melinda, Opitz Andrea, Madanian Hadi

Publikováno v: Journal of Space Weather and Space Climate, Vol 9, p A3 (2019)

Aims: The solar wind pressure is an important parameter of space weather, which plays a crucial role in the interaction of the solar wind with the planetary plasma environment. Here we investigate the possibility of determining a solar wind pressure

Hot flow anomaly remnant in the far geotail?

Autor: Facskó, Gábor, Opitz, Andrea, Lavraud, Benoit, Luhmann, Janet G., Russell, Christopher T., Sauvaud, Jean-Andre, Fedorov, Andrei, Kis, Árpád, Wesztergom, Viktor

A hot flow anomaly (HFA) like event was observed by the Solar TErrestrial RElations Observatory (STEREO) in the night side magnetosheath in the far tail in February-March 2007. The magnetic signature of the tangential discontinuity was visible, but t

STEREO measurements of electron acceleration beyond fast Fermi at the bow shock

Autor: Pulupa, Marc, Bale, Stuart D., Opitz, Andrea, Fedorov, Andrei, Lin, Robert P., Sauvaud, Jean-Andre

Solar wind electrons are accelerated and reflected upstream by the terrestrial bow shock into a region known as the electron foreshock. Previously observed electron spectra at low energies are consistent with a fast Fermi mechanism, based on the adia
