Proposal Title: A Search for Cyclotron Maser Emission from Extrasolar Planets
ABSTRACT:
Radio frequency cyclotron maser radiation is emitted by all ve of our solar system's magnetized planets. Given a
source of energetic (keV) electrons, such as a stellar wind, it is likely that magnetized extrasolar planets also
produce this intense nonthermal radiation. We propose a search for cyclotron maser emission from known
extrasolar planets, targeting those planets with the largest predicted radio uxes at 0.327, 1.4 and 5 GHz. The
detection of such radiation would be the rst detection of radio emission from an extrasolar planet, and would
possibly be the rst direct detection of an extrasolar planet at any wavelength. The analysis of such a detection
would also provide otherwise unobtainable information about the planetary magnetosphere. The sensitivity of the
Arecibo telescope and the large catalog of known extrasolar planets from which to choose appropriate candidates
give the proposed search an advantage over previous searches, which produced no detections.
