Like Jupiter, most of the extra-solar giant planets are probably magnetized and they should also emit radio emission. We have searched for possible radio emission towards all known extra-solar planetary systems using the TIFR GMRT Sky Survey Alternative Data Release at 150 MHz. Radio emission is not detected from most of the extra-solar planets but it is detected from few star systems which harbor Jupiter size extra-solar planet. Strong magnetic field is required for sustained radio emission from planets and magnetic field in planet may be important for life to exist in the surface of the planet as it keeps away effects of energetic particles of cosmic rays, stellar winds and stellar flares. Here we will briefly summarize our findings. |
