Rippled quasiperpendicular shock observed by the magnetospheric multiscale spacecraft

Rippled quasiperpendicular shock observed by the magnetospheric multiscale spacecraft
Rippled quasiperpendicular shock observed by the magnetospheric multiscale spacecraft
Collisionless shock nonstationarity arising from microscale physics influences shock structure and particle acceleration mechanisms. Nonstationarity has been difficult to quantify due to the small spatial and temporal scales. We use the closely spaced (subgyroscale), high-time-resolution measurements from one rapid crossing of Earth’s quasiperpendicular bow shock by the Magnetospheric Multiscale (MMS) spacecraft to compare competing nonstationarity processes. Using MMS’s high-cadence kinetic plasma measurements, we show that the shock exhibits nonstationarity in the form of ripples.

Abstract

Collisionless shock nonstationarity arising from microscale physics influences shock structure and particle acceleration mechanisms. Nonstationarity has been difficult to quantify due to the small spatial and temporal scales. We use the closely spaced (subgyroscale), high-time-resolution measurements from one rapid crossing of Earth’s quasiperpendicular bow shock by the Magnetospheric Multiscale (MMS) spacecraft to compare competing nonstationarity processes. Using MMS’s high-cadence kinetic plasma measurements, we show that the shock exhibits nonstationarity in the form of ripples.
