A Cross-Laboratory Comparison Study of Titan Haze Analogs: Surface Energy II
Eric C. Austin, Xinting Yu, Chao He +10
The organic haze particles on Titan play important roles in atmospheric cloud formation and aerosol-lake interactions. These processes are strongly influenced by the surface energy…
Unlocking accretion rate diagnostics for high-mass protostars using JWST/MIRI HI lines
S. D. Reyes-Reyes, H. Beuther, E. F. van Dishoeck +14
While many aspects of high-mass star formation have been investigated, the accretion onto the central protostars is one of the most fundamental but less explored physical propertie…
Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets
Joshua Krissansen-Totton, Anna Grace Ulses, Maxwell Frissell +21
Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insuf…
Three-stage Formation of Cap Carbonates after Marinoan Snowball Glaciation Consistent with Depositional Timescales and Geochemistry
Trent B. Thomas, David C. Catling
At least two global "Snowball Earth" glaciations occurred during the Neoproterozoic Era (1000-538.8 million years ago). Post-glacial surface environments during this time are recor…
A reassessment of the "hard-steps" model for the evolution of intelligent life
Daniel B. Mills, Jennifer L. Macalady, Adam Frank +1
According to the "hard-steps" model, the origin of humanity required "successful passage through a number of intermediate steps" (so-called "hard" or "critical" steps) that were in…
Inferring Chemical Disequilibrium Biosignatures for Proterozoic Earth-Like Exoplanets
Amber V. Young, Tyler D. Robinson, Joshua Krissansen-Totton +9
Chemical disequilibrium quantified via available free energy has previously been proposed as a potential biosignature. However, exoplanet biosignature remote sensing work has not y…
