Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy
Mark A. Johnson, Jose R. Montes-Bojorquez, Adis Husic +7
Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Sa…
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…
Probing Cold-to-Temperate Exoplanetary Atmospheres: The Role of Water Condensation on Surface Identification with JWST
Ziyu Huang, Xinting Yu, Shang-Min Tsai +5
Understanding the surface temperature and interior structure of cold-to-temperate sub-Neptunes is critical for assessing their habitability, yet direct observations are challenging…
The Fate of Simple Organics on Titan's Surface: A Theoretical Perspective
Xinting Yu, Yue Yu, Julia Garver +2
Atmospheric photochemistry on Titan continuously transforms methane and nitrogen gases into various organic compounds. This study explores the fate of these molecules when they lan…
Material Properties of Organic Liquids, Ices, and Hazes on Titan
Xinting Yu, Yue Yu, Julia Garver +5
Titan has a diverse range of materials in its atmosphere and on its surface: the simple organics that reside in various phases (gas, liquid, ice) and the solid complex refractory o…
Microphysics of Water Clouds in the Atmospheres of Y Dwarfs and Temperate Giant Planets
James Mang, Peter Gao, Callie E. Hood +4
Water clouds are expected to form on Y dwarfs and giant planets with equilibrium temperatures near or below that of Earth, drastically altering their atmospheric compositions and t…
Cleaning our Hazy Lens: Exploring Trends in Transmission Spectra of Warm Exoplanets
Austin H. Dymont, Xinting Yu, Kazumasa Ohno +3
Relatively little is understood about the atmospheric composition of temperate to warm exoplanets (equilibrium temperature 1000 K), as many of them are found to have…
Haze Evolution in Temperate Exoplanet Atmospheres Through Surface Energy Measurements
Xinting Yu, Chao He, Xi Zhang +13
Photochemical hazes are important opacity sources in temperate exoplanet atmospheres, hindering current observations from characterizing exoplanet atmospheric compositions. The haz…
Surface Energy of the Titan Aerosol Analog "Tholin"
Xinting Yu, Sarah Horst, Chao He +3
The photochemical haze produced in the upper atmosphere of Titan plays a key role in various atmospheric and surface processes on Titan. The surface energy, one important physical…
Haze Formation in Warm H2-rich Exoplanet Atmospheres
Chao He, Sarah M. Horst, Nikole K. Lewis +8
New observing capabilities coming online over the next few years will provide opportunities for characterization of exoplanet atmospheres. However, clouds/hazes could be present in…
Sulfur-driven Haze Formation in Warm CO2-rich Exoplanet Atmospheres
Chao He, Sarah M. Horst, Nikole K. Lewis +8
Sulfur gases significantly affect the photochemistry of planetary atmospheres in our Solar System, and are expected to be important components in exoplanet atmospheres. However, su…
Single particle triboelectrification of Titan sand analogs
Xinting Yu, Sarah M. Horst, Chao He +1
Sand electrification is important for aeolian sediment transportation on terrestrial bodies with silicate sand as the main sediment composition. However, it has not been thoroughly…
Where does Titan Sand Come From: Insight from Mechanical Properties of Titan Sand Candidates
Xinting Yu, Sarah M. Hörst, Chao He +2
Extensive equatorial linear dunes exist on Titan, but the origin of the sand, which appears to be organic, is unknown. We used nanoindentation to study the mechanical properties of…
Photochemical Haze Formation in the Atmospheres of super-Earths and mini-Neptunes
Chao He, Sarah M. Horst, Nikole K. Lewis +8
UV radiation can induce photochemical processes in exoplanet atmospheres and produce haze particles. Recent observations suggest that haze and/or cloud layers could be present in t…
