Abstract

Magnetised exoplanets are expected to emit at radio frequencies, similarly to the radio auroral emission of Earth and Jupiter. We predict the radio emission from V830 Tau b, the youngest (2 Myr) detected exoplanet to date, and investigate whether its radio emission can propagate through the stellar wind plasma. We model the wind of the host star using 3D MHD simulations that take into account the reconstructed stellar surface magnetic field. We find that, although stellar winds can power radio emission from exoplanets, if the planet orbits inside the radio photosphere of the stellar wind, then the wind will prevent the propagation of planetary radio emission.
