Cluster and MMS simultaneous observations of magnetosheath high speed jets and their impact on the magnetopause

CP Escoubet, KJ Hwang, S Toledo-Redondo… - Frontiers in Astronomy …, 2020 - frontiersin.org
When the supersonic solar wind encounters the Earth's magnetosphere a shock, called bow
shock, is formed and the plasma is decelerated and thermalized in the magnetosheath …

Jets in the magnetosheath: IMF control of where they occur

L Vuorinen, H Hietala, F Plaschke - Annales geophysicae, 2019 - angeo.copernicus.org
Magnetosheath jets are localized regions of plasma that move faster towards the Earth than
the surrounding magnetosheath plasma. Due to their high velocities, they can cause …

Investigating the anatomy of magnetosheath jets–MMS observations

T Karlsson, F Plaschke, H Hietala… - Annales …, 2018 - angeo.copernicus.org
We use Magnetosphere Multiscale (MMS) mission data to investigate a small number of

On the generation of magnetosheath high‒speed jets by bow shock ripples

H Hietala, F Plaschke - Journal of Geophysical Research …, 2013 - Wiley Online Library
The terrestrial magnetosheath is embedded with coherent high‒speed jets of about 1RE in
scale, predominantly during quasi‒radial interplanetary magnetic field (IMF). When these …

Statistical study of magnetosheath jet‐driven bow waves

TZ Liu, H Hietala, V Angelopoulos… - Journal of …, 2020 - Wiley Online Library

ambient magnetosheath at a (relative) speed faster than the local magnetosonic speed, a …

Causes of jets in the quasi‐perpendicular magnetosheath

P Kajdič, S Raptis, X Blanco‐Cano… - Geophysical Research …, 2021 - Wiley Online Library
Magnetosheath jets are currently an important topic in the field of magnetosheath physics. It
is thought that 97% of the jets are produced by the shock rippling at quasi‐parallel shocks …

Supermagnetosonic subsolar magnetosheath jets and their effects: From the solar wind to the ionospheric convection

H Hietala, N Partamies, TV Laitinen… - Annales …, 2012 - angeo.copernicus.org
