The Role of Gyrating Ions in Reformation of a Quasi-parallel Supercritical Shock

The Astrophysical Journal
Collisionless shocks in space and astrophysical plasmas mediate energy exchange between charged particles and fields in two or more plasma flows. In this study we analyze the evolution of ion distributions around a reformation cycle of a quasi-parallel ...

The Martian electron foreshock, based on Mars Global Surveyor's measurements

, 2003
The Martian electron foreshock position and shape have been revealed using electron flux data obtained by the Electron Reflectometer (ER) experiment on board Mars Global Surveyor, in the time period between days 87 and 118 of 1998. From the electron flux

Transient upstream mesoscale structures: drivers of solar-quiet space weather

Frontiers in Astronomy and Space Sciences
In recent years, it has become increasingly clear that space weather disturbances can be triggered by transient upstream mesoscale structures (TUMS), independently of the occurrence of large-scale solar wind (SW) structures, such as interplanetary ...

Field‐Aligned Currents Induced by Magnetopause Motions Under Pressure Perturbations

Geophysical Research Letters
In this work, we identified 65 auroral arcs that stretched out from the equatorward boundary of auroral oval with azimuthal extensions, and investigated their upstream triggering, by utilizing conjunctions between the THEMIS probes and the all‐sky ...

Radio Emissions from Earth’s Foreshock and Bolides

, 2021
It is well understood that Earth’s foreshock radiation is due to the bow shock deflecting the solar wind and accelerating electrons upstream into the foreshock where they produce Langmuir waves and radio emissions.

Two‐Dimensional Motions of Diffuse Auroral Patches Under Upstream Dynamic Pressure Enhancements of the Bow Shock

Geophysical Research Letters
In this study, we identified 51 dayside diffuse auroral patches and examined their two‐dimensional evolutions by using the Time History of Events and Macroscale Interactions during Substorms probes and the ground‐based all‐sky imager at the South Pole ...

Immediate foreshock–mainshock arise from a paused model

Despite the growing wealth of seismic observations, the physics of earthquake initiation remains elusive. And foreshocks offer one of the few direct observational constraints on this process.
