Simulating the Escaping Atmosphere of GJ 436 b with Two-fluid Magnetohydrodynamic Models

Lei Xing, Jianheng Guo, Chuyuan Yang +1

Observations of transmission spectra reveal that hot Jupiters and Neptunes are likely to possess escaping atmospheres driven by stellar radiation. Numerous models predict that magn…

A possibly solar metallicity atmosphere escaping from HAT-P-32b revealed by H and He absorption

Dongdong Yan, Jianheng Guo, Kwang-il Seon +3

This paper presents a hydrodynamic simulation that couples detailed non-local thermodynamic equilibrium (NLTE) calculations of the hydrogen and helium level populations to model th…

Long-term double synchronization in close-in gas giant planets

Shuaishuai Guo, Jianheng Guo, Jie Su +1

Hot Jupiters, orbiting their host stars at extremely close distances, undergo tidal evolution, with some being engulfed by their stars due to angular momentum exchanges induced by…

The Mass Fractionation of Helium in the Escaping Atmosphere of HD 209458b

Lei Xing, Dongdong Yan, Jianheng Guo

The absorption signals of metastable He in HD 209458b and several other exoplanets can be explained via escaping atmosphere model with a subsolar He/H ratio. The low abundance of h…

Modeling H and He 10830 transmission spectrum of WASP-52b

Dongdong Yan, Kwang-il Seon, Jianheng Guo +2

Escaping atmosphere has been detected by the excess absorption of Ly, H and He triplet (10830) lines. Simultaneously modeling the absorption of the H and He 10830 li…

Atmosphere escape inferred from modelling the H transmission spectrum of WASP-121b

Dongdong Yan, Jianheng Guo, Chenliang Huang +1

The escaping atmospheres of hydrogen driven by stellar X-ray and extreme Ultraviolet (XUV) have been detected around some exoplanets by the excess absorption of Ly in far ultrav…
