Inferring and Interpreting the Visual Geometric Albedo and Phase Function of Earth
Tyler D. Robinson
Understanding reflectance-related quantities for worlds enables effective comparative planetology and strengthens mission planning and execution. Measurements of these properties f…
The Open-Source Photochem Code: A General Chemical and Climate Model for Interpreting (Exo)Planet Observations
Nicholas F. Wogan, Natasha E. Batalha, Kevin Zahnle +7
With the launch of the James Webb Space Telescope, we are firmly in the era of exoplanet atmosphere characterization. Understanding exoplanet spectra requires atmospheric chemical…
Extreme Forward Scattering Observed in Disk-Averaged Near-Infrared Phase Curves of Titan
Chase A. Cooper, Tyler D. Robinson, Jason W. Barnes +2
Titan, with its thick and hazy atmosphere, is a key world in our solar system for understanding light scattering processes. NASA's Cassini mission monitored Titan between 2004 and…
Modern Earth-like Chemical Disequilibrium Biosignatures Are Challenging To Constrain Through Spectroscopic Retrievals
Amber Young, Tyler Robinson, Joshua Krissansen-Totton +4
Robust exoplanet characterization studies are underway, and the community is looking ahead toward developing observational strategies to search for life beyond our solar system. Wi…
Potential technosignature from anomalously low deuterium/hydrogen (D/H) in planetary water depleted by nuclear fusion technology
David C. Catling, Joshua Krissansen-Totton, Tyler D. Robinson
Deuterium-deuterium (DD) fusion is viewed as an ideal energy source for humanity in the far future, given a vast seawater supply of D. Here, we consider long-lived, extraterrestria…
Microphysical Prescriptions for Parameterized Water Cloud Formation on Ultra-cool Substellar Objects
James Mang, Caroline V. Morley, Tyler D. Robinson +1
Water must condense into ice clouds in the coldest brown dwarfs and exoplanets. When they form, these icy clouds change the emergent spectra, temperature structure, and albedo of t…
