We present and validate a new network of atmospheric thermochemical and photochemical sulfur reactions. We use a 1D chemical kinetics model to investigate these reactions as part of a broader HCNO chemical network in a series of hot and warm Jupiters. We find that temperatures approaching $1400\, \mathrm{K}$ are favourable for the production of H2S and HS around $\mathrm{10^{-3}\, bar}$ at mixing ratios of around 10−5, an atmospheric level where detection by transit spectroscopy may be… 
Linking Atmospheric Chemistry of the Hot Jupiter HD 209458b to Its Formation Location through Infrared Transmission and Emission Spectra
The elemental ratios of carbon, nitrogen, and oxygen in the atmospheres of hot Jupiters may hold clues to their formation locations in the protostellar disk. In this work, we adopt gas-phase chemical
Proposed energy-metabolisms cannot explain the atmospheric chemistry of Venus
Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its
Spectroscopic Characterization of HSO2• and HOSO• Intermediates Involved in SO2 Geoengineering.
TLDR
Assignment of the UV-vis spectra is consistent with the photochemistry of HOSO• and HSO2• as observed by matrix-isolation IR spectroscopy and also by the agreement with high-level ab initio calculations.
Photochemistry of Venus-like Planets Orbiting K- and M-dwarf Stars
Compared to the diversity seen in exoplanets, Venus is a veritable astrophysical twin of the Earth; however, its global cloud layer truncates features in transmission spectroscopy, masking its
A Comparative Study of Atmospheric Chemistry with VULCAN
We present an update of the open-source photochemical kinetics code VULCAN to include C–H–N–O–S networks and photochemistry. The additional new features are advection transport, condensation, various

Biological oceanography: Sulphur, climate and the microbial maze
TLDR
A connection between climate and marine algae comes from the algal production of a sulphur-containing compound, dimethylsulphoniopropionate, and the action of one of the resulting products as a defence mechanism is described.
They used a flow discharge with SO2 and H2O, and found k = 6.95
