Abstract

Collisionless shock non-stationarity arising from micro-scale physics influences shock structure and particle acceleration mechanisms. Non-stationarity has been difficult to quantify due to the small spatial and temporal scales. We use the closely-spaced (sub-gyroscale), high time-resolution measurements from one rapid crossing of Earth's quasi-perpendicular bow shock by the Magnetospheric Multiscale (MMS) spacecraft to compare competing non-stationarity processes. Using MMS's high cadence kinetic plasma measurements, we show that the shock exhibits non-stationarity in the form of ripples.
