Most Rocky Sub-Neptunes are Molten: Mapping the Solidification Shoreline for Gas Dwarf Exoplanets
Robb Calder, Oliver Shorttle, Harrison Nicholls +2
Sub-Neptunes are the most common type of detected exoplanet, yet their observed masses and radii are degenerate with several interior structures. One possibility is that sub-Neptun…
Re-accretion of Giant Impact Ejecta Can Drive Significant Atmospheric Erosion on Terrestrial Planets
Tuhin Ghosh, Mark Wyatt, Oliver Shorttle
Giant impacts, the collisions between planetary embryos, play a crucial role in sculpting the planets and their orbital architectures. Numerical simulations have advanced our under…
Constraining exoplanet interiors using observations of their atmospheres
Tim Lichtenberg, Oliver Shorttle, Johanna Teske +1
Astronomical surveys have identified numerous exoplanets with bulk compositions that are unlike the planets of the Solar System, including rocky super-Earths and gas-enveloped sub-…
Powerful lightning on Venus constrained by atmospheric NO
Tereza Constantinou, Oliver Shorttle, Paul B. Rimmer
Signs of lightning on Venus have long been sought, including by space missions and ground-based telescopes searching for optical flashes, plasma waves, or radio signatures. These e…
Can tidal evolution lead to close-in planetary bodies around white dwarfs II: volcanism and transits
Yuqi Li, Amy Bonsor, Oliver Shorttle
Planetary material accreted by white dwarfs provides unique insights regarding exoplanetary composition. The evolutionary pathways of planetary bodies around white dwarfs are cruci…
Can tidal evolution lead to close-in planetary bodies around white dwarfs I: Orbital period distribution
Yuqi Li, Amy Bonsor, Oliver Shorttle +1
The evolution of planetary systems around white dwarfs is crucial to understanding the presence of planetary material in the atmospheres of white dwarfs. These systems uniquely pro…
Abiotic Ozone in the Observable Atmospheres of Venus and Venus-like Exoplanets
Robb Calder, Oliver Shorttle, Sean Jordan +2
Ozone is a potential biosignature and disambuguator between Earth-like and Venus-like exoplanets due to its association on Earth with photosynthetically produced oxygen (O). Ho…
Comparative biosignatures with systemic retrievals
Tereza Constantinou, Oliver Shorttle, Miles Cranmer +1
The discovery of inhabited exoplanets hinges on identifying biosignature gases. JWST can reveal biosignature gases, though current discoveries have yet to evidence life. The centra…
Refractory phosphorus in the HD 100546 protoplanetary disk
Mihkel Kama, Oliver Shorttle, Sandipan P. D. Borthakur +5
The phosphorus budget of planets is intertwined with their formation history and is thought to influence their habitability. The chemical reservoirs and volatile \emph{vs} refracto…
Planetary albedo is limited by the above-cloud atmosphere: Implications for sub-Neptune climate
Sean Jordan, Oliver Shorttle, Sascha P. Quanz
Energy limits that delineate the `habitable zone' for exoplanets depend on a given exoplanet's net planetary albedo (or `Bond albedo'). We here demonstrate that the planetary albed…
Tracing the Inner Edge of the Habitable Zone with Sulfur Chemistry
Sean Jordan, Oliver Shorttle, Paul B. Rimmer
The circumstellar liquid-water habitable zone guides our search for potentially inhabited exoplanets, but remains observationally untested. We show that the inner edge of the habit…
