Seasonal Variability of Pluto's Haze Formation Revealed by Laboratory Simulations
Zhengbo Yang, Chao He, Yu Liu +9
Pluto possesses a thin atmosphere primarily composed of N2, with minor constituents including CO and CH4. Photochemical processes generate distinct haze layers as observed by the N…
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…
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…
Laboratory Simulations of Haze Formation in the Atmospheres of super-Earths and mini-Neptunes: Particle Color and Size Distribution
Chao He, Sarah M. Horst, Nikole K. Lewis +7
Super-Earths and mini-Neptunes are the most abundant types of planets among the ~3500 confirmed exoplanets, and are expected to exhibit a wide variety of atmospheric compositions.…
