Atmospheric Supply of Hydrogen Cyanide Is Not the Rate-limiting Step for Prebiotic Chemistry across Rocky Exoplanets

Gergely Friss, Paul I. Palmer, Marrick Braam +1

Hydrogen cyanide (HCN) is crucial for the RNA World hypothesis, forming biomolecules essential for early life. Life likely emerged around 4 billion years ago during the early Arche…

Hydrocarbon complexity and photochemical shielding of prebiotic feedstock molecules in exoplanet atmospheres

Marrick Braam, Ellery Gopaoco, Shang-Min Tsai +4

The potential of prebiotic chemistry to propagate on an exoplanet fundamentally depends on whether the atmospheric conditions can facilitate the production of prebiotic feedstock m…

The Oxygen Valve on Hydrogen Escape Since the Great Oxidation Event

Gregory J. Cooke, Dan R. Marsh, Catherine Walsh +2

The Great Oxidation Event (GOE) was a Myr transition circa 2.4 billion years ago that converted the Earth's anoxic atmosphere to one where molecular oxygen (O) was abunda…

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…

Earth-like exoplanets in spin-orbit resonances: climate dynamics, 3D atmospheric chemistry, and observational signatures

Marrick Braam, Paul I. Palmer, Leen Decin +3

Terrestrial exoplanets around M- and K-type stars are important targets for atmospheric characterisation. Such planets are likely tidally locked with the order of spin-orbit resona…

Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood

Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62

The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
