Thermal Structure of Planetary Ionospheres
1973Electrons released in the photoionization process due to the absorption of solar XUV radiation in planetary atmospheres may have initially kinetic energies of one to 100 eV. The energy E of photoelectrons resulting from photons of energy h v interacting with an atmospheric constituent whose ionization potential is IP is given by $$E = hv - IP ...

The Composition and Structure of Planetary Rings
1985The properties of planetary ring systems are summarized herein; emphasis is given to the available evidence on their compositions and to their dynamical attributes. Somewhat contaminated water ice makes up the vast expanse of Saturn’s rings. Modified methane ice may comprise Uranus’ rings while silicates are the likely material of the Jovian ring ...
