Magnetic Flux Transport Identification of Active Reconnection: MMS Observations in Earth's Magnetosphere
Yi Qi, Tak Chu Li, Christopher T. Russell +3
Magnetic reconnection plays an important role in converting energy while modifying field topology. This process takes place in varied plasma environments in which the transport of…
The brittle boulders of dwarf planet Ceres
Stefan Schröder, Uri Carsenty, Ernst Hauber +2
We mapped all boulders larger than 105 m on the surface of dwarf planet Ceres using images of the Dawn framing camera acquired in the Low Altitude Mapping Orbit (LAMO). We find tha…
Comparative study of electric currents and energetic particle fluxes in a solar flare and Earth magnetospheric substorm
Anton Artemyev, Ivan Zimovets, Ivan Sharykin +20
Magnetic field-line reconnection is a universal plasma process responsible for the conversion of magnetic field energy to the plasma heating and charged particle acceleration. Sola…
Electrostatic solitary waves in the Earth's bow shock: nature, properties, lifetimes and origin
R. Wang, I. Y. Vasko, F. S. Mozer +4
We present a statistical analysis of more than two thousand bipolar electrostatic solitary waves (ESW) collected from ten quasi-perpendicular Earth's bow shock crossings by Magneto…
In situ evidence of ion acceleration between consecutive reconnection jet fronts
Filomena Catapano, Alessandro Retino, Gaetano Zimbardo +21
Processes driven by unsteady reconnection can efficiently accelerate particles in many astrophysical plasmas. An example are the reconnection jet fronts in an outflow region. We pr…
Whistler Waves in the foot of Quasi-Perpendicular Super-Critical Shocks
Ahmad Lalti, Yuri Khotyaintsev, Daniel B. Graham +3
Whistler waves are thought to play an essential role in the dynamics of collisionless shocks. We use the magnetospheric multiscale (MMS) spacecraft to study whistler waves around t…
The boulder population of asteroid 4 Vesta: Size-frequency distribution and survival time
Stefan E. Schröder, Uri Carsenty, Ernst Hauber +3
Dawn's framing camera observed boulders on the surface of Vesta when the spacecraft was in its lowest orbit (LAMO). We identified, measured, and mapped boulders in LAMO images, whi…
Direct Measurement of the Solar-Wind Taylor Microscale using MMS Turbulence Campaign Data
Riddhi Bandyopadhyay, William H. Matthaeus, Alexandros Chasapis +7
Using the novel Magnetospheric Multiscale (MMS) mission data accumulated during the 2019 MMS Solar Wind Turbulence Campaign, we calculate the Taylor microscale o…
Interplay of Turbulence and Proton-Microinstability Growth in Space Plasmas
Riddhi Bandyopadhyay, Ramiz A. Qudsi, William H. Matthaeus +13
Numerous prior studies have shown that as proton beta increases, a narrower range of proton temperature anisotropy values is observed. This effect has often been ascribed to the ac…
In situ Measurement of Curvature of Magnetic Field in Turbulent Space Plasmas: A Statistical Study
Riddhi Bandyopadhyay, Yan Yang, William H. Matthaeus +10
Using in situ data, accumulated in the turbulent magnetosheath by the Magnetospheric Multiscale (MMS) Mission, we report a statistical study of magnetic field curvature and discuss…

Riddhi Bandyopadhyay, Luca Sorriso-Valvo, Alexandros Chasapis +13
We present estimates of the turbulent energy cascade rate, derived from a Hall-MHD third-order law. We compute the contribution from the Hall term and the MHD term to the energy fl…
