Spatial variation of the 3.29 and 3.40 micron emission bands within reflection nebulae and the photochemical evolution of methylated polycyclic aromatic hydrocarbons
TL;DR: It is suggested that a photochemical evolution of the initial aliphatic and aromatic hydrocarbon mixture formed in the outflow is responsible for the changes observed in the 3 micrometers emission spectra of these objects.
Infrared spectroscopy of Nova Cassiopeiae 1993 ¿ IV. A closer look at the dust
TL;DR: In this article, the spectral energy distribution (SED) with the DUSTY code was used to determine the properties and geometry of the emitting dust shell of a nova, which has a carbon:silicate ratio of 2:1 by number and a relatively flat size distribution.
Very Large Excesses of 18 O in Hydrogen-deficient Carbon and R Coronae Borealis Stars: Evidence for White Dwarf Mergers
TL;DR: In this paper, it was shown that WD mergers may very well be the progenitors of O18-rich R Coronae Borealis (RCB) and HdC stars.
The abundance of AsH3 in Jupiter
TL;DR: In this article, both ground-based and airborne observations of the AsH3 Q-branch at 2126/cm, in conjunction with newly-analyzed laboratory comparison spectra at ASH3, are employed in the derivation of a new estimate of Jovian As abundance.

TL;DR: In this paper, the first published spatially resolved images of Neptune's thermal emission were taken at the Gemini North telescope, showing enhanced methane and ethane emission within 30° of the south pole.
