Radiation sputtering of hydrocarbon ices at Europa-relevant temperatures
Sankhabrata Chandra, Bryana L. Henderson, Murthy S. Gudipati
The surfaces of some icy moons, such as Jupiter's moon Europa, are heavily bombarded by energetic particles that can alter the surface materials and affect the composition of its e…

Electron-induced chemistry and sputtering of volatile species from amorphous and crystalline water ice
Yogeshwar Nath Mishra, Sankhabrata Chandra, Murthy S. Gudipati +3
Electron irradiation of water-rich ices plays a significant role in initiating the chemical and physical processes on the surface of airless icy bodies in radiation environments su…

Electron-induced CO2 and hydrocarbon sputtering of functionalized hydrocarbons in icy planetary analogs
Sankhabrata Chandra, Bryana L. Henderson, Murthy S. Gudipati
CO2 has been detected in both the tenuous exosphere and surface chaos regions of Europa, but it is still unclear whether this CO2 is generated in situ by radiolysis or whether it i…
