Magnetosheath jet evolution as a function of lifetime: global hybrid-Vlasov simulations compared to MMS observations [PDF]
Annales Geophysicae, 2021 Magnetosheath jets are regions of high dynamic pressure, which can traverse from the bow shock towards the magnetopause. Recent modelling efforts, limited to a single jet and a single set of upstream conditions, have provided the first estimations about ...

MeV magnetosheath ions energized at the bow shock [PDF]
, 2001 A causal relationship between midlatitude magnetosheath energetic ions and bow shock magnetic geometry was previously established for ion energy up to 200 keV e−1 for the May 4, 1998, storm event.

Ion Larmor radius effects near a reconnection X line at the magnetopause: THEMIS observations and simulation comparison [PDF]
, 2016 We report a Time History of Events and Macroscale Interactions during Substorms (THEMIS-D) spacecraft crossing of a magnetopause reconnection exhaust ~9 ion skin depths (di) downstream of an X line. The crossing was characterized by ion jetting at speeds

Magnetosheath jet properties and evolution as determined by a global hybrid-Vlasov simulation [PDF]
Annales Geophysicae, 2018 We use a global hybrid-Vlasov simulation for the magnetosphere, Vlasiator, to investigate magnetosheath high-speed jets. Unlike many other hybrid-kinetic simulations, Vlasiator includes an unscaled geomagnetic dipole, indicating that the simulation ...

Impact of Foreshock Transients on the Flank Magnetopause and Magnetosphere and the Ionosphere
Frontiers in Astronomy and Space Sciences, 2021 Mesoscale (on the scales of a few minutes and a few RE) magnetosheath and magnetopause perturbations driven by foreshock transients have been observed in the flank magnetotail.

Asymmetric magnetic reconnection with a flow shear and applications to the magnetopause [PDF]
, 2015 We perform a theoretical and numerical study of anti-parallel 2D magnetic reconnection with asymmetries in the density and reconnecting magnetic field strength in addition to a bulk flow shear across the reconnection site in the plane of the reconnecting

Interball-1 observations of flux transfer events [PDF]
Annales Geophysicae, 2012 We present the results of a survey of 807 FTEs observed by Interball-1 on the mid- and high-latitude dayside and flank magnetopause. Dayside magnetosheath events show a strong tendency to occur for southward magnetosheath magnetic fields suggesting ...

Coherent wave activity in Mercury's magnetosheath [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractThis study presents a statistical overview of coherent wave activity in Mercury's magnetosheath. Left‐handed electromagnetic ion cyclotron waves are commonly found behind the quasi‐perpendicular section of the bow shock, where they are present in ~50% of the spacecraft crossings of the magnetosheath.

Rotation of the magnetic field in Earth's magnetosheath by bulk magnetosheath plasma flow [PDF]
Annales Geophysicae, 2006 Abstract. Orientations of the observed magnetic field in Earth's dayside magnetosheath are compared with the predicted field line-draping pattern from the Kobel and Flückiger static magnetic field model. A rotation of the overall magnetosheath draping pattern with respect to the model prediction is observed. For an earthward Parker spiral, the sense of
