Abstract

We estimate possible radio emission of massive exoplanets and brown dwarfs. We assume that such radiation originates in processes similar to those observed in the Jupiter system. Therefore, we analyse two possible emission scenarios. The first scenario assumes interaction between the stellar wind and the planetary magnetosphere. The second mechanism needs a moon orbiting close to the planet, and is similar to the Jupiter-Io interaction. We show that the emission of exoplanets and brown dwarfs, in young systems (age < 0.1 Gyr) can be observed even at GHz frequencies. Therefore, VLBI networks could possibly detect such radiation. Moreover, an excellent angular resolution of VLBI should also allow to observe orbital movement in nearby (distance < 30 pc) systems.

dwarfs. We assume that such radiation originates in processes similar
to those observed in the Jupiter system. Therefore, we analyse two
possible emission scenarios. The first scenario assumes interaction
between the stellar wind and the planetary magnetosphere. The second
mechanism needs a moon orbiting close to the planet, and is similar
to the Jupiter-Io interaction. We show that the emission of
exoplanets and brown dwarfs, in young systems (age < 0.1 Gyr) can be
observed even at GHz frequencies. Therefore, VLBI networks could
possibly detect such radiation. Moreover, an excellent angular
resolution of VLBI should also allow to observe orbital movement in
nearby (distance < 30 pc) systems.
