Charged Ejecta Clouds from Granular Beds after Slow Impacts

The Planetary Science Journal
Low-velocity impacts are a significant process on all planetary surfaces, from rebounding particles on asteroids to saltating grains on Earth. Due to triboelectric effects, the material involved can be charged. We carried out experiments to study the net

The Dehydration of Serpentines and Extraction of Water

The Planetary Science Journal
Some groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,

3 μm Phase Curves of Main-belt Asteroids from NEOWISE Photometry

The Planetary Science Journal
The shapes of asteroid phase curves are influenced by the physical properties of asteroid surfaces. The variation of an asteroid’s brightness as a function of the solar phase angle can tell us about surface properties such as grain size distribution ...
