Haze Formation on Triton
Kazumasa Ohno, Xi Zhang, Ryo Tazaki +1
The largest moon of Neptune, Triton, possess a cold and hazy atmosphere. Since the discovery of near-surface haze layer during the Voyager fly in 1989, the haze formation mechanism…
3D simulations of photochemical hazes in the atmosphere of hot Jupiter HD 189733b
Maria E Steinrueck, Adam P. Showman, Panayotis Lavvas +3
Photochemical hazes have been suggested as candidate for the high-altitude aerosols observed in the transmission spectra of many hot Jupiters. We present 3D simulations of the hot…
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…
The Science Case for a Titan Flagship-class Orbiter with Probes
Conor A. Nixon, James Abshire, Andrew Ashton +36
We outline a flagship-class mission concept focused on studying Titan as a global system, with particular emphasis on the polar regions. Investigating Titan from the unique standpo…
Atmospheric Regimes and Trends on Exoplanets and Brown Dwarfs
Xi Zhang
A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance among the first and most accessible planetary layers observed from space, it is close…
A Global Non-Hydrostatic Atmospheric Model with a Mass and Energy Conserving Vertically-Implicit-Correction (VIC) Scheme
Huazhi Ge, Cheng Li, Xi Zhang +1
Global non-hydrostatic atmospheric models are becoming increasingly important for studying the climates of planets and exoplanets. However, such models suffer from computational di…
Revisiting the Sulfur-Water Chemical System in the Middle Atmosphere of Venus
Wencheng D. Shao, Xi Zhang, Carver J. Bierson +1
Sulfur-water chemistry plays an important role in the middle atmosphere of Venus. Ground based observations have found that simultaneously observed SO2 and H2O at ~64 km vary with…
Aerosol Composition of Hot Giant Exoplanets Dominated by Silicates and Hydrocarbon Hazes
Peter Gao, Daniel P. Thorngren, Elspeth K. H. Lee +6
Aerosols are common in the atmospheres of exoplanets across a wide swath of temperatures, masses, and ages. These aerosols strongly impact observations of transmitted, reflected, a…
Deflating Super-Puffs: Impact of Photochemical Hazes on the Observed Mass-Radius Relationship of Low Mass Planets
Peter Gao, Xi Zhang
The observed mass-radius relationship of low-mass planets informs our understanding of their composition and evolution. Recent discoveries of low mass, large radii objects ("super-…
