  journal={Space Science Reviews},
Magnetospheric ions, solar wind ions, and locally produced pick-up ions can impact the atmospheres of objects in the solar system, transferring energy by collisions with atmospheric atoms and molecules. This can result in an expansion of the atmospheric corona with a fraction of the energetic atoms or molecules being lost (sputtered) from the atmosphere. The expanded corona presents a larger target to the incident plasma, which in turn enhances pick-up ion formation and collisional ejection. In… Expand
Energetic ions from the solar wind, local pick-up ions or magnetospheric plasma ions impact the atmospheres and surfaces of a number of solar system bodies. These energetic incident ions depositExpand
Sputter contribution to the atmospheric corona on Mars
Pickup-ion-induced sputtering, a potentially important nonthermal loss mechanism for the atmosphere of Mars, will also increase the content of the oxygen corona. This atmospheric sputtering processExpand
