Modeling Low-Temperature Plasmas Simulating Titan’s Atmosphere
In the study presented here, we model the gas phase chemistry induced by plasma discharge at low temperature (150 K) in the NASA Ames COSmIC Simulation Chamber (COSmIC) using a […]

Constraints On Europa’s Water Group Torus From HST/COS Observations
In-situ plasma measurements as well as remote mapping of energetic neutral atoms around Jupiter provide indirect evidence that an enhancement of neutral gas is present near the orbit of the […]
