Polarimetry in Planetary Sciences and Astronomy
C. H. Lucas Patty, Jonathan Grone, Brice-Olivier Demory +7
In recent decades, the relevance of polarimetry in planetary sciences and astronomy has increased rapidly. Polarization is a fundamental property of light and can be modified by an…
Experimental evidence for granular shear-flow instability in the Epstein regime
Holly L. Capelo, Jean-David Bodénan, Martin Jutzi +7
Stability analysis of two-fluid protoplanetary disc models has enriched our understanding of how solids can grow into larger bodies called planetesimals. Dust particles entrained i…
Climates of Terrestrial Exoplanets and Biosignatures
Siddharth Bhatnagar, Emeline Bolmont, Nikita J. Boeren +18
Understanding the climates of terrestrial exoplanets and the detectability of biosignatures is an inherently interdisciplinary challenge, requiring the integration of insights from…
Evolution of granular salty ice analogs for Europa: Sublimation and Irradiation
Rafael Ottersberg, Antoine Pommerol, Linus Leo Stöckli +5
We study the evolution of the Vis-NIR reflectance spectrum of salty granular ice analog samples in a simulation chamber under conditions relevant to the surface of Europa. A novel…
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…
