Lightning activity on a tidally locked terrestrial exoplanet in storm-resolving simulations for a range of surface pressures
Denis E. Sergeev, James W. McDermott, Lottie Woods +3
Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules into reactive species and thereby af…
Impacts of UV Radiation from an AGN on Planetary Atmospheres and Consequences for Galactic Habitability
Kendall I. Sippy, Jake K. Eager-Nash, Ryan C. Hickox +2
We present a study of the effects of ultraviolet (UV) emission from active galactic nuclei (AGN) on the atmospheric composition of planets and potential impact on life. It is expec…
Biosignatures from pre-oxygen photosynthesising life on TRAPPIST-1e
Jake K. Eager-Nash, Stuart J. Daines, James W. McDermott +13
In order to assess observational evidence for potential atmospheric biosignatures on exoplanets, it will be essential to test whether spectral fingerprints from multiple gases can…
3D simulations of the Archean Earth including photochemical haze profiles
M. T. Mak, N. J. Mayne, D. E. Sergeev +5
We present results from 3D simulations of the Archean Earth including a prescribed (non-interactive) spherical haze generated through a 1D photochemical model. Our simulations sugg…
3D climate simulations of the Archean find that methane has a strong cooling effect at high concentrations
Jake K. Eager-Nash, Nathan J. Mayne, Arwen E. Nicholson +11
Methane is thought to have been an important greenhouse gas during the Archean, although its potential warming has been found to be limited at high concentrations due to its high s…
Predicting biosignatures for nutrient limited biospheres
A. E. Nicholson, S. J. Daines, N. J. Mayne +3
With the characterisations of potentially habitable planetary atmospheres on the horizon, the search for biosignatures is set to become a major area of research in the coming decad…
