Studies of Jovian Radio Emission and the Search for Extrasolar Planets/Space Weather

The discovery of planetary radio emission from Jupiter 66 years ago marked the beginning of a new way to explore our solar system. This low frequency emission is powered by the interaction of the Jovian magnetosphere with the Solar wind and Galilean moon Io. All magnetized planets in the solar system have been detected through low frequency emission from their magnetospheres. Study of this emission allows not only the identification of the presence of planetary magnetic fields but also provies an estimate of the planetary field strength. I will present recent studies of Jovian decametric emission from the Long Wavelength Array".

Planetary magnetic fields may play a critical role in determining the habitability of a planet by shielding the surface from cosmic rays and the stellar wind. The search for exoplanet radio emission and space weather has come to the forefront with the development of new sensitive low frequency instruments and calibration techniques. I will highlight a few of the recent exciting results in this field.
