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…

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…

The escape of hydrogen-rich atmosphere of exoplanet: Mass loss rates and the absorptions of stellar Lyman
Dongdong Yan, Jianheng Guo
Since the mass loss rates are the function of the mean density of the planet and the stellar irradiation, we calculated about 450 models covering planets with different densities a…
