RADIOASTRONOMICAL ASPECTS IN THE SEARCH FOR EXTRASOLAR PLANETS

摘要

In analogy to our solar system in which Jupiter with a dominating planetary magnetic field acts as a powerful radio emitter, it is reasonable that giant exoplanets exhibit comparable radiation in the decametric wavelength regime. State-of-the-art instrumentation incorporated in huge ground-based radio telescopes may be able to discover these electromagnetic signatures, applying sophisticated observational methods. Some of these aspects are addressed in view of recent developments.
