Stellar-Planet Interaction: Accretion from planetary wind

Colombo, Salvatore; Pillitteri, Ignazio; Orlando, Salvatore; Micela, Giuseppina

Hot Jupiters are perfect laboratories to study the processes of stellar-planet interaction. Due to their mass and proximity to the central star, the atmospheres of hot Jupiters are heated by the stellar radiation and, in some cases, they photoevaporate. The stellar wind is the medium where the planetary outflow expands. In this work, we model the interaction of the planetary wind with the star extended corona. We aim to understand whether this interaction may result in an enhanced stellar activity.
