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…
Influence of CO versus CH on organic haze formation in atmospheres of diverse terrestrial exoplanets
Sai Wang, Zhengbo Yang, Haixin Li +9
Context. Terrestrial exoplanets are expected to host secondary, high-metallicity atmospheres derived from outgassing of volatiles such as N2, CO2, H2O, CH4, and CO. Photochemical o…
Quantifying Building Blocks of Life in Planetary Analog Materials: Implications for Prebiotic Chemistry and Biosignature Identification
Xiaoou Luo, Chao He, Zhengbo Yang +5
Building blocks of life such as amino acids, nucleobases, and fatty acids are central to prebiotic chemistry and represent key targets in the search for planetary biosignatures. In…
The impact of organic hazes and graphite on the observation of CO2-rich sub-Neptune atmospheres
Haixin Li, Chao He, Sai Wang +9
Many sub-Neptune and super-Earth exoplanets are expected to develop metal-enriched atmospheres due to atmospheric loss processes such as photoevaporation or core-powered mass loss.…
Formation of organic hazes in CO-rich sub-Neptune atmospheres within the graphite-stability regime
Sai Wang, Zhengbo Yang, Chao He +10
Super-Earths and sub-Neptunes are the most common exoplanets, with a "radius valley" suggesting that super-Earths may form by shedding sub-Neptunes' gaseous envelopes. Exoplanets t…
