Atmospheric Dynamics of Asymmetrically Magnetized Hot Jupiter
Miaoyin Tang, Cong Yu
We investigate the influence of asymmetric magnetic fields on the atmospheric circulation of hot Jupiters based on a Shallow-Water Magnetohydrodynamic (SWMHD) model. The Shallow-Wa…
Sub-Neptunes Show a Stronger Correlation with Cold Jupiters than Super-Earths Especially in Metal-rich Systems
Di-Chang Chen, Fei Dai, Bo Ma +2
Correlations between the inner small planets and cold giants encodes the formation and evolution of planetary systems. It remains unclear if the correlation differs on the two side…
Constraining the presence of exotrojans in hot Jupiter systems using TTV observations from TESS
Zixin Zhang, Wenqin Wang, Xinyue Ma +8
Co-orbital bodies (Trojans) share a 1:1 mean-motion resonance with a planet. Although Trojans are common in the Solar System, none has yet been confirmed in an exoplanetary system.…
Fates of the sub-stellar objects (FOSSO) I. Fates of the known brown dwarfs in main-sequence--BD binaries
Zhangliang Chen, Hongming Jin, Hongwei Ge +4
Context. Understanding the survival and orbital evolution of brown dwarf (BD) companions during the post-main-sequence (MS) evolution of their host stars is increasingly important,…
Evidence for a Nonzero Eccentricity Superpuff Exoplanet WASP-107 b Using JWST Occultation Observation
Yunke Wu, Zixin Zhang, Xinyue Ma +6
WASP-107~b is an extremely low-density super-puff exoplanet whose inflated radius and evidence of strong internal heating make it a key target for understanding planetary structure…
Irradiated Atmosphere V: Effects of Vertical-Mixing induced Energy Transport on the Inhomogeneity
Wei Zhong, Zhen-Tai Zhang, Bo Ma +3
Atmospheric variations over time and space boost planetary cooling, as outgoing internal flux responds to stellar radiation and opacity. Vertical mixing regulates this cooling. Our…
