Interactions of planets with evolved stars

An ever increasing number of exoplanets have been detected around post-main sequence stars over the past few years. Depending on their masses and orbital periods, these sub-stellar companions can strongly impact the mass loss from evolved stars, enhancing and shaping it. The stellar winds also impact the exoplanets; when the star evolves to the giant phase, frozen planets may ‘thaw’, shifting the habitable zone outwards, while others heat-up, e.g., Jupiter may become a hot Jupiter. The wind may evaporate the planetary atmosphere, and/or pollute it, while also producing radio emission that may be detectable with SKA. In this project, the latest and most detailed hydrodynamic and radiative transfer codes will be used to investigate the interaction of exoplanets with the dense stellar winds ejected by evolved stars.
