Density-Selected Topological Pathways in the Melting of Single-Particle-Thick Stripes
José Rafael Bordin
The melting of stripe-forming systems involves changes in connectivity that are not fully captured by conventional structural and orientational descriptors. We investigate a two-di…
Detecting habitable exoplanet atmospheres with LIFE, the Large Interferometer for Exoplanets
Sarah Rugheimer, Aiden Weatherbee, James Fecanin +21
A key goal of astronomers with the next generation telescopes is to detect signs of life in exoplanet atmospheres. NASA's next flagship is the Habitable Worlds Observatory (HWO). I…
Organosulfur Chemistry on sub-Neptunes: Implications for hazes and biosignatures
Sean Jordan, Shang-Min Tsai, Paul B. Rimmer +1
The organosulfur biosignature gases dimethylsulfide (DMS) and dimethlydisulfide (DMDS) have recently been claimed to be present in the atmosphere of sub-Neptune exoplanet K2-18b, l…
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…
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…
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…
