Woo, R., 1993, "Solar Cycle Variation of Interplanetary Disturbances Observed as Doppler Scintillation Transients", https://hdl.handle.net/2014/35209, Journal of Geophysical Research, JPL Open Repository
Interplanetary disturbances characterized by plasma that is more turbulent and/or moves faster than the background solar wind are readily detected as transients in Doppler scintillation measurements of the near-Sun solar wind. |

Krisher, T. P., 1993, "The Parametrized Post-Newtonian Gravitational Redshift", https://hdl.handle.net/2014/35215, Physical Review D, JPL Open Repository
A derivation of the gravitational redshift effect to order c ^(-4) is presented. The calculation isperformed within the framework of the parametrized post-Newtonian formalism for analyzing metrictheories of gravity, which includes corrections to second- order in the Newtonian pot... |

Penprase, Bryan E.; Helou, George, 1993, "IR Properties of Galactic Cirrus Near The Polar Caps", https://hdl.handle.net/2014/35838, Tucson, Arizona, JPL Open Repository
We present a systematic study of the infrared properties of the high galactic latitude sky, by examining two large sections of the IRAS Sky Survey, which cover galactic latitudes from b=20 to b=90, and b=-20 to b=-90, at a reduced resolution of 7.5'/pixel. The IRAS Sky Survey Atl... |

Gautier, T. N.; Stewart, W., 1993, "(abstract) Spatial Power Spectral Measurements of IR Cirrus", https://hdl.handle.net/2014/35149, Tucson, AZ, JPL Open Repository
We have used recently released IRAS Sky Survey Atlas (ISSA) image data to investigate the surface brightness distribution of selected regions of infrared cirrus using power spectral analysis techniques. |

Gautier, T. N., 1993, "Cirrus and Future Space Based Astronomy", https://hdl.handle.net/2014/35845, Tucson, AZ, JPL Open Repository
Astronomical observations from space make possible observations of sensitivity and spatial resolution impossible in the past. This increase in sensitivity will both make possible the observation of new phenomena and will bring observations against limitations not encountered befo... |

Gautier, T.N., 1993, "(abstract) Infrared Cirrus and Future Space Based Astronomy", https://hdl.handle.net/2014/35150, Tucson, AZ, JPL Open Repository
A review of the known properties of the distribution of infrared cirrus is followed by a discussion of the implications of cirrus on observations from space. Probable limitations on space observations due to IR cirrus |

Werner, M.W.; Gauthier, T. N. III.; Cawlfield, T., 1993, "Stability of Small Grains in HII Regions and Reflection Nebulae", https://hdl.handle.net/2014/35549, Tucson, AZ, JPL Open Repository
We have analyzed IRAS data to assess the relative amounts of small and large grains in HII regions and reflection nebulae. Our most important finding is that no evidence for small grain destruction is seen in reflection nebulae, even for [high] values of the radiation energy dens... |
