Abstract:

SEVERAL INVESTIGATORS HAVE proposed photometric methods of detecting extrasolar planets. The luminosity of the planet in the visible portion of the spectrum is about 10^-9 that of the primary for a Jovian size planet (0.001 solar masses and 0.1 the solar radius) radiating reflected light from the solar-type star. The luminosity of such a planet in the infrared due to internally generated thermal radiation at about 100° K will be about 10^-4 that of the primary in the same part of the spectrum. Thus, one is looking in these methods for some direct anomalous radiation component associated with a star even though it is small. We consider yet another process for generating the radiation.
