Electron-Induced Radiolysis of Water Ice and the Buildup of Oxygen
Chantal Tinner, André Galli, Fiona Bär +4
Irradiation by energetic ions, electrons, and UV photons induces sputtering and chemical processes (radiolysis) in the surfaces of icy moons, comets, and icy grains. Laboratory exp…
Sputter Yields of the Lunar Surface: Experimental Validation and Numerical Modelling of Solar Wind Sputtering of Apollo 16 Soils
Johannes Brötzner, Herbert Biber, Paul Stefan Szabo +12
Sputtering by solar wind ions is a key process driving the ejection of high-energy particles into the exospheres of airless bodies like asteroids, Mercury and the Moon. In view of…
Callisto's atmosphere: First evidence for H2 and constraints on H2O
Shane R. Carberry Mogan, Orenthal J. Tucker, Robert E. Johnson +8
We explore the parameter space for the contribution to Callisto's H corona observed by the Hubble Space Telescope (Roth et al. 2017a) from sublimated H2O and radiolytically produce…
A tenuous, collisional atmosphere on Callisto
Shane Carberry Mogan, Orenthal Tucker, Robert Johnson +7
A simulation tool which utilizes parallel processing is developed to describe molecular kinetics in 2D, single-and multi-component atmospheres on Callisto. This expands on our prev…
Three-Dimensional Modeling of Callisto's Surface Sputtered Exosphere Environment
Audrey Vorburger, Martin Pfleger, Jesper Lindkvist +6
We study the release of various elements from Callisto's surface into its exosphere by plasma sputtering. The cold Jovian plasma is simulated with a 3D plasma-planetary interaction…
An Impacting Descent Probe for Europa and the other Galilean Moons of Jupiter
P. Wurz, D. Lasi, N. Thomas +10
We present a study of an impacting descent probe that increases the science return of spacecraft orbiting or passing an atmosphere-less planetary body of the solar system, such as…
