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…
New compound and hybrid binding energy sputter model for modeling purposes in agreement with experimental data
Noah Jäggi, Andreas Mutzke, Herbert Biber +5
Rocky planets and moons experiencing solar wind sputtering are continuously supplying their enveloping exosphere with ejected neutral atoms. To understand the quantity and properti…
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…
Evolution of Mercury's Earliest Atmosphere
Noah Jäggi, Diana Gamborino, Dan J. Bower +6
MESSENGER observations suggest a magma ocean formed on proto-Mercury, during which evaporation of metals and outgassing of C- and H-bearing volatiles produced an early atmosphere.…
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…
