Sputtering: In the context of space weathering on the surfaces of airless planetary bodies, sputtering is the process in which atoms on the surface are knocked free by high-speed atomic particles in the solar wind; ...
magnetron sputtering (NASA Thesaurus) A deposition method in which a microwave tube is utilized to confine a plasma magnetically to produce high deposition rates and a low working-gas partial pressure.
[citation needed] Another important source is generated through the process of sputtering, which involves the bombardment of micrometeorites, solar wind ions, electrons, and sunlight.
Other molecules escape into space through a process of atmospheric sputtering.
Unlike a light bulb which emits a pretty constant amount of in a certain amount of time, Cyg X-1 is constantly fluctuating; emitting bursts of energy then flickering and sputtering, all in an apparently random manner.
Processes such as vaporisation of rocks by impacts, evaporation of elements from rocks, sputtering by solar wind ions or diffusion from the planet's interior contribute to it.
An exosphere is a super-low-density atmosphere probably formed, in this case, from atoms sputtering off Mercury's surface. The sputtering may be caused by contact with hot plasma trapped in Mercury's magnetic field.
Other mechanisms that can cause atmosphere depletion are solar wind-induced sputtering, impact erosion, weathering, and sequestration — sometimes referred to as "freezing out" — into the regolith and polar caps.

Explorer 7 was designed to measure solar x-ray and Lyman-alpha flux, trapped energetic particles, and heavy primary cosmic rays (Z>5). Secondary objectives included collecting data on micrometeoroid penetration and molecular sputtering and studying ...
Processes such as vaporization of surface rocks during impacts, evaporation of elements from the surface when exposed to sunlight, sputtering from solar wind, or diffusion from the planet's interior, may all play a role.
This phase is likely to be short-lived because (1) so few clusters show such far-IR sources, (2) grains have relatively short lifetimes against sputtering by such energetic impacts, ...
sputtering Dislocation of surface atoms of a material from bombardment by high-energy atomic particles. square wave 1. An oscillation, the amplitude of which shows periodic discontinuities between two values, remaining constant between jumps.
