Ultraviolet photometry from the Orbiting Astronomical Observatory. XIII. The albedo of Jupiter, Uranus, and Neptune.
Abstract
This paper presents OAO2 broadband ultraviolet photometry data for Jupiter, Uranus, and Neptune. These data have been combined with observations of 23 latetype stars to derive planetary albedos over the region A. The new broadband albedo for Jupiter agrees well with a previous measurement based on OAO2 spectrometer data. The albedos for Uranus and Neptune are in good agreement with ground measurements in the region of overlap. The results for Uranus and Neptune have been compared with theoretical calculations for semiinfinite and finite pure H2 RayleighRaman scattering atmospheres. Except for the shortest wavelengths, the measurements lie below the semiinfinite theoretical calculations. The calculations for the finite atmospheres suggest that an additional absorbing constituent will be needed to explain the observed albedos.
