Characterisation of the upper atmosphere of HD 209458 b by means of helium triplet absorption spectra
.The upper atmosphere of HD 209458 b undergoes hydrodynamic escape that is the most atmospheric efficient mass-loss process. Previous works on its characterisation were mainly based on the available Ly-α observations, which provide limited information due to the interstellar medium absorption and the geocoronal emission contamination, and then a
