Atmospheric Circulation of High-Obliquity Mini-Neptunes
Yanhong Lai, Xianyu Tan, Yubo Su
With the operation of JWST, atmospheric characterization has now extended to low-mass exoplanets. In compact multiplanetary systems, secular spin-orbital resonance may preserve hig…
Irradiated Atmospheres I: Heating by Vertical-Mixing Induced Energy Transport
Wei Zhong, Zhen-Tai Zhang, Hui-Sheng Zhong +3
Observations have revealed unique temperature profiles in hot Jupiter atmospheres. We propose that the energy transport by vertical mixing could lead to such thermal features. In o…
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…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems II: A 1 to 20 Micron Spectrum of the Planetary-Mass Companion VHS 1256-1257 b
Brittany E. Miles, Beth A. Biller, Polychronis Patapis +101
We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a 20 M widely separated (8\arcsec, a = 150 au), young, planetary-…
