- Abstract
An approach to detect the Neptune-size and large terrestial-like bodies was discussed. A detailed connection between the hydrodynamic treatment and non-thermal pick up ion loss simulations were also studied. It was observed that the large exoplanets orbiting close to their central star have either migrated inward from greater distances or have formed at their present orbit. It was found that the Neptune-class exoplanets because of the higher stellar irradiance and stellar wind in the past could loose their entire hydrogen atmospheres due to non-thermal and thermal escape processes.
