A Fast, Parallelized, GPU-Accelerated Photochemical Model, XODIAC, with Built-in Equilibrium Chemistry and Multiple Chemical Networks for Exoplanetary Atmospheres
Priyankush Ghosh, Sambit Mishra, Shubham Dey +3
The launch of the James Webb Space Telescope (JWST) has delivered high-quality atmospheric observations and expanded the known chemical inventory of exoplanetary atmospheres, openi…
Constraining the survival of HCN during cometary impacts
Catriona H. McDonald, Amy Bonsor, Auriol S. P. Rae +3
Cometary impacts have been invoked as an atmosphere-independent method of stockpiling hydrogen cyanide (HCN), a key prebiotic feedstock molecule, into environments favourable for t…
The atmospheric entry of cometary impactors
Richard J Anslow, Amy Bonsor, Zoe R Todd +4
Cometary impacts play an important role in the early evolution of Earth, and other terrestrial exoplanets. Here, we present a numerical model for the interaction of weak, low-densi…
The plausibility of origins scenarios requiring two impactors
Richard J Anslow, Amy Bonsor, Paul B Rimmer +3
Hydrogen cyanide delivered by cometary impactors can be concentrated as ferrocyanide salts, which may support the initial stages of prebiotic chemistry on the early Earth. One way…
Can comets deliver prebiotic molecules to rocky exoplanets?
Richard J. Anslow, Amy Bonsor, Paul B. Rimmer
In this work we consider the potential of cometary impacts to deliver complex organic molecules and the prebiotic building blocks required for life to rocky exoplanets. Numerical e…
Atomic iron and titanium in the atmosphere of the exoplanet KELT-9b
H. Jens Hoeijmakers, David Ehrenreich, Kevin Heng +10
The chemical composition of an exoplanet is a key ingredient in constraining its formation history. Iron is the most abundant transition metal, but has never been directly detected…
The Peculiar Atmospheric Chemistry of KELT-9b
Daniel Kitzmann, Kevin Heng, Paul B. Rimmer +6
The atmospheric temperatures of the ultra-hot Jupiter KELT-9b straddle the transition between gas giants and stars, and therefore between two traditionally distinct regimes of atmo…
Detection of OH and HO towards Orion~KL
H. Gupta, P. Rimmer, J. C. Pearson +76
We report observations of the reactive molecular ions OH, HO, and HO towards Orion KL with Herschel/HIFI. All three fine-structure transitions of OH…
Herschel/HIFI observations of interstellar OH+ and H2O+ towards W49N: a probe of diffuse clouds with a small molecular fraction
D. A. Neufeld, J. R. Goicoechea, P. Sonnentrucker +50
We report the detection of absorption by interstellar hydroxyl cations and water cations, along the sight-line to the bright continuum source W49N. We have used Herschel's HIFI ins…
Interstellar OH+, H2O+ and H3O+ along the sight-line to G10.6-0.4
Maryvonne Gerin, M. De Luca, John Black +50
We report the detection of absorption lines by the reactive ions OH+, H2O+ and H3O+ along the line of sight to the submillimeter continuum source G10.60.4 (W31C). We used the He…
