Reformation of Supercritical Perpendicular Shock
Yuri V. Khotyaintsev, Domenico Trotta, Daniel B. Graham
Super-critical collisionless shocks are not static structures but evolve continuously as they reflect incoming ions back upstream. The physical process responsible for this non-sta…
Occurrence of Non-Stationarity at Earth's Quasi-Perpendicular Bow Shock
Ajay Lotekar, Yuri V. Khotyaintsev, Daniel B. Graham +3
Collisionless shocks can exhibit non-stationary behavior even under steady upstream conditions, forming a complex transition region. Ion phase-space holes, linked to shock self-ref…
Debye-scale electrostatic waves across quasi-perpendicular shocks
Ahmad Lalti, Yuri V. Khotyaintsev, Daniel B. Graham +1
The evolution of the properties of short-scale electrostatic waves across collisionless shocks remains an open question. We use a method based on the interferometry of the electric…
Ion-Acoustic Waves and the Proton-Alpha Streaming Instability at Collisionless Shocks
Daniel B. Graham, Yuri V. Khotyaintsev, Ahmad Lalti
Ion-acoustic waves are routinely observed at collisionless shocks and could be an important source of resistivity. The source of instability and the effects of the waves are not fu…
Electron Heating by Parallel Electric Fields in Magnetotail Reconnection
Louis Richard, Yuri V. Khotyaintsev, Cecilia Norgren +5
We investigate electron heating by magnetic-field-aligned electric fields () during anti-parallel magnetic reconnection in the Earth's magnetotail. Using a statistical…
Electron-scale energy transfer due to lower hybrid waves during asymmetric reconnection
Sabrina F. Tigik, Daniel B. Graham, Yuri V. Khotyaintsev
We use Magnetospheric Multiscale (MMS) mission data to investigate electron-scale energy transfer due to lower hybrid drift waves during magnetopause reconnection. We analyze waves…
Electron heating at quasi-perpendicular collisionless shocks
Ahmad Lalti, Yuri V. Khotyaintsev, Daniel B. Graham
Adiabatic and non-adiabatic electron dynamics have been proposed to explain electron heating across collisionless shocks. We analyze the evolution of the suprathermal electrons acr…
Ion Reflection by a Rippled Perpendicular Shock
Yuri V. Khotyaintsev, Daniel B. Graham, Andreas Johlander
We use multi-spacecraft Magnetospheric Multiscale (MMS) observations to investigate electric fields and ion reflection at a non-stationary collisionless perpendicular plasma shock.…
Turbulence in Magnetic Reconnection Jets from Injection to Sub-Ion Scales
L. Richard, L. Sorriso-Valvo, E. Yordanova +2
We investigate turbulence in magnetic reconnection jets in the Earth's magnetotail using data from the Magnetospheric Multiscale spacecraft. We show that signatures of a limited in…
Sub-ion scale Compressive Turbulence in the Solar wind: MMS spacecraft potential observations
Owen Wyn Roberts, Rumi Nakamura, Klaus Torkar +9
Compressive plasma turbulence is investigated at sub-ion scales in the solar wind using both the Fast Plasma Investigation (FPI) instrument on the Magnetospheric MultiScale mission…
Turbulence and Transport During Guide-Field Reconnection at the Magnetopause
L. Price, M Swisdak, J. F. Drake +1
We analyze the development and influence of turbulence in three-dimensional particle-in-cell simulations of guide-field magnetic reconnection at the magnetopause with parameters ba…
Universality of lower hybrid waves at Earth's magnetopause
D. B. Graham, Yu. V. Khotyaintsev, C. Norgren +15
Waves around the lower hybrid frequency are frequently observed at Earth's magnetopause, and readily reach very large amplitudes. Determining the properties of lower hybrid waves i…
Magnetospheric Multiscale Dayside Reconnection Electron Diffusion Region Events
J. M. Webster, J. L. Burch, P. H. Reiff +21
We have used the high-resolution data of the Magnetospheric Multiscale (MMS) mission dayside phase to identify twenty-one previously unreported encounters with the electron diffusi…
