A Foreshock Bubble Driven by an IMF Tangential Discontinuity: 3D Global Hybrid Simulation
Journal ArticleDOI
Hybrid Simulations of a Tangential Discontinuity‐Driven Foreshock Bubble Formation in Comparison With a Hot Flow Anomaly Formation
TL;DR: In this article , the authors investigated the formation of tangential discontinuity (TD)-driven foreshock ions and hot flow anomalies (HFAs) using 2-D local hybrid simulations where a reflected or an injected warm foreshock ion beam can interact with a TD whose half-thickness is comparable to the ion inertial scale.
Statistical Study of Favorable Foreshock Ion Properties for the Formation of Hot Flow Anomalies and Foreshock Bubbles
TL;DR: In this paper , the authors performed a statistical study of foreshock ion properties around 275 hot flow anomalies (HFAs) and foreshock bubbles (FBs) and found that foreshock ions with a high foreshock-to-solar wind density ratio (>∼3), high kinetic energy >∼600 eV, and large ratio of kinetic energy to thermal energy (> ∼0.4) favor HFA and FB formation.

TL;DR: The THEMIS Fluxgate Magnetometer (FGM) as discussed by the authors was designed to study abrupt reconfigurations of the Earth's magnetosphere during the substorm onset phase and is capable of detecting variations of the magnetic field with amplitudes of 0.01 nT.

James P. McFadden,C. W. Carlson,Davin Larson,M. Ludlam,R. Abiad,B. Elliott,Paul Turin,M. Marckwordt,Vassilis Angelopoulos +8 more
TL;DR: The THEMIS instrument as discussed by the authors is designed to measure the ion and electron distribution functions over the energy range from a few eV up to 30 keV for electrons and 25 kV for ions, and it consists of a pair of electrostatic analyzers with common 180°×6° fields-of-view that sweep out 4π steradians each 3 s spin period.
