Auroras are (generally) high‐latitude atmospheric emissions that result from the precipitation
of energetic charged particles from a planet's magnetosphere. Auroral emissions from the …

This review covers the work of the three decades since the first spectroscopic identification
of the H 3+ molecular ion outside of the laboratory in 1988, in the auroral atmosphere of the …

A new hot line list is calculated for 12CH4 in its ground electronic state. This line list, called
10to10, contains 9.8 billion transitions and should be complete for temperatures up to 1500 …

ABSTRACT A new hot line list for 14NH3 is presented. The line list CoYuTe was constructed
using an accurate, empirically refined potential energy surface and a CCSD (T)/aug-cc …

We present an improved model for interplanetary dust grain fluxes in the outer Solar System
constrained by in situ dust density observations. A dynamical dust grain tracing code is used …

Calculations are reported on the rotation− vibration energy levels of ammonia with
associated transition intensities. A potential energy surface obtained from coupled cluster …

Spectral imaging is an interdis-ciplinary approach encompassing chemistry, physics, and
engineering. It is used to visualize the chemical composition of materials and is a window …

Ultraviolet spectra obtained with the Hubble Space Telescope identified at least 10
molecules and atoms in the perturbed stratosphere near the G impact site, most never …

Evidence for the collision of fragmented comets or asteroids with some of the larger (jovian)
planets and their moons is now well established following the dramatic impact of the …

Two months after the discovery of comet Shoemaker-Levy 9 came the astonishing
announcement that the comet would impact Jupiter in July 1994. Computing the orbital …
