Identifiable Acetylene Features Predicted for Young Earth-like Exoplanets with Reducing Atmospheres undergoing Heavy Bombardment
P. B. Rimmer, M. Ferus, I. P. Waldmann +14
The chemical environments of young planets are assumed to be largely influenced by impacts of bodies lingering on unstable trajectories after the dissolution of the protoplanetary…
Statistical analysis of Curiosity data shows no evidence for a strong seasonal cycle of Martian methane
Ed Gillen, Paul B Rimmer, David C Catling
Using Gaussian Process regression to analyze the Martian surface methane Tunable Laser Spectrometer (TLS) data reported by Webster (2018), we find that the TLS data, taken as a who…
A chemical kinetics code for modelling exoplanetary atmospheres
R. Hobbs, O. Shorttle, N. Madhusudhan +1
Chemical compositions of exoplanets can provide key insights into their physical processes, and formation and evolutionary histories. Atmospheric spectroscopy provides a direct ave…
A spectral survey of an ultra-hot Jupiter: Detection of metals in the transmission spectrum of KELT-9 b
H. J. Hoeijmakers, D. Ehrenreich, D. Kitzmann +16
Context: KELT-9 b exemplifies a newly emerging class of short-period gaseous exoplanets that tend to orbit hot, early type stars - termed ultra-hot Jupiters. The severe stellar irr…
Lightning and charge processes in brown dwarf and exoplanet atmospheres
Christiane Helling, Paul B Rimmer
The study of the composition of brown dwarf atmospheres helped to understand their formation and evolution. Similarly, the study of exoplanet atmospheres is expected to constrain t…
Hydrogen Cyanide in Nitrogen-Rich Atmospheres of Rocky Exoplanets
Paul B. Rimmer, Sarah Rugheimer
Hydrogen cyanide (HCN) is a key feedstock molecule for the production of life's building blocks. The formation of HCN in an N-rich atmospheres requires first that the triple bo…
Nitrogen Oxide Concentrations in Natural Waters on Early Earth
Sukrit Ranjan, Zoe R. Todd, Paul B. Rimmer +2
A key challenge in origins-of-life studies is estimating the abundances of species relevant to the chemical pathways proposed to have contributed to the emergence of life on early…
Origin of life's building blocks in Carbon and Nitrogen rich surface hydrothermal vents
Paul B Rimmer, Oliver Shorttle
There are two dominant and contrasting classes of origin of life scenarios: those predicting that life emerged in submarine hydrothermal systems, where chemical disequilibrium can…
Stellar Flares from the First Tess Data Release: Exploring a New Sample of M-dwarfs
Maximilian N. Günther, Zhuchang Zhan, Sara Seager +21
We perform a study of stellar flares for the 24,809 stars observed with 2 minute cadence during the first two months of the TESS mission. Flares may erode exoplanets' atmospheres a…
