| Description: | "Radio emission from planets: The solar system and beyond" by Jean-Mathias Griessmeier All interested are welcome at 11:00 in the Hooghoudt room. Abstract: Planetary radio emission has been a field of major interest since the early days of radio astronomy. A variety of different emission processes occur at planets: Thermal emission has been measured since the 1950s, the magnetospheric radio emission of Jupiter was discovered in 1955, later Jupiter's snychrotron radiation was studied, and planetary lightning was detected by Voyager in 1980. Beyond the solar system, radio emission produced by extrasolar planets is actively searched for by several groups. Detection has not yet been achieved, but estimations indicate that the increased sensitivity of new receivers and the construction of large radio telescopes (e.g. LOFAR) should allow a detection in the near future. |
