Searching for Life-As-We-Don't-Know-It: Mission-relevant Application of Assembly Theory for Exoplanet Life Detection
Sara Walker, Estelle Janin, Evgenya Shkolnik +2
This white paper introduces a framework for applying Assembly Theory (AT) to planetary atmospheres as a biosignature framework suitable for the Habitable Worlds Observatory (HWO).…
Direct imaging characterization of cool gaseous planets
Michiel Min, Jo Barstow, Laura C. Mayorga +19
Cool gas giant exoplanets, particularly those with properties similar to those of Jupiter and Saturn, remain poorly characterized due to current observational limitations. This whi…
The PEPSI Exoplanet Transit Survey (PETS). V: New Na D transmission spectra indicate a quieter atmosphere on HD 189733b
E. Keles, S. Czesla, K. Poppenhaeger +23
Absorption lines from exoplanet atmospheres observed in transmission allow us to study atmospheric characteristics such as winds. We present a new high-resolution transit time-seri…
Strong fractionation of deuterium and helium in sub-Neptune atmospheres along the radius valley
Collin Cherubim, Robin Wordsworth, Renyu Hu +1
We simulate atmospheric fractionation in escaping planetary atmospheres using IsoFATE, a new open-source numerical model. We expand the parameter space studied previously to planet…
The PEPSI Exoplanet Transit Survey (PETS) IV: Assessing the atmospheric chemistry of KELT-20b
Sydney Petz, Marshall C. Johnson, Anusha Pai Asnodkar +11
Most ultra hot Jupiters (UHJs) show evidence of temperature inversions, in which temperature increases with altitude over a range of pressures. Temperature inversions can occur whe…
