We present initial results of a new campaign of simulations focusing on the interaction of
planetary winds with stellar environments using Adaptive Mesh Refinement methods. We
have confirmed the results of Stone & Proga (2009) that an azimuthal flow structure is
created in the planetary wind due to day/night temperatures differences. We show that a
backflow towards the planet will occur with a strength that depends on the escape
parameter. When a stellar outflow is included, we see unstable bow waves forming through …
We present initial results of a new campaign of simulations focusing on the interaction of planetary winds with stellar environments using Adaptive Mesh Refinement methods. We have confirmed the results of Stone & Proga (2009) that an azimuthal flow structure is created in the planetary wind due to day/night temperatures differences. We show that a backflow towards the planet will occur with a strength that depends on the escape parameter. When a stellar outflow is included, we see unstable bow waves forming through the outflow's interaction with the planetary wind.
