Covering state-of-the-art advances, novel applications, and future perspectives, this volume
presents new directions on the basic studies of charged particle and photon interactions with …

Aeronomy is a description of the physics and chemistry of the upper atmospheres and
ionospheres of planetary bodies. In this chapter we consider those processes occurring in …

We present the first UV airglow observations of Titan's atmosphere by the Ultraviolet Imaging
Spectrograph (UVIS) on Cassini. Using one spectral channel in the EUV from 561–1182 Å …

Most of Titan's atmospheric organic and nitrogen chemistry, aerosol formation, and
atmospheric loss are driven from external energy sources such as Solar UV, Saturn's …

Atomic-physics calculations of radiative cooling are used to develop criteria for the
overstability of radiating shocks. Our calculations explain the measurement of shock …

The first determination of the 15N/14N ratio in Titan's atmosphere comes from Earth-based
millimetric wavelength spectroscopic observations of HC15N/HC14N. These measurements …

We have measured the 30 and 100 eV far ultraviolet (FUV) emission cross sections of the
optically allowed Fourth Positive Group (4PG) band system (A1Π→ X1Σ+) of CO and the …

This paper carefully examines the inability of photochemical models to account for the large
nitric oxide densities of∼ 108 cm− 3 at∼ 105 km obtained from IR, UV, and microwave …

A detailed analysis of the mechanisms heating Titan's neutral atmosphere is provided. Two
primary sources of incoming energy, the solar photons and the energetic electrons from …

We report electron-impact-induced medium resolution fluorescence spectra of CO [310 Å
and 366 Å full width at half maximum (FWHM)] at 100 eV over the spectral region from 1300 …
