Detecting nonsolar planets by spinning infrared interferometer

  title={Detecting nonsolar planets by spinning infrared interferometer},
  author={Ronald N. Bracewell},
THE only known planets are the nine in our Solar System, so the origin of the Solar System and of stars in general would be clarified if other planetary systems could be discovered. Likewise, speculation about life in the Galaxy would benefit from knowing which stars have planets. Astrometry, radial velocity measurement, and direct photography from orbit might detect planets, but none of these approaches will be easy. Astrometry would require detection of the motion of a stellar image, relative… CONTINUE READING
