Christian Seelos,Kate Ganly,Johanna Mair path between trail particles suggests that the Comet Rendevous/Asteroid Flyby mission is unlikely to be affected if it flies within the trail ahead of the comet in its orbit, but may collide with trail particles (having diameters of a few hundred microns) behind the comet.

Separating the solar system and galactic contributions to the diffuse infrared background,suggest that the outer edge is located near the edge of the asteroid belt, that the grains absorb and radiate like blackbodies, and that the density is consistent with Poynting-Robertson drag on grains originating in the asteroid belt.

The albedo of large refractory particles from p/Tempel 2, path between trail particles suggests that the Comet Rendevous/Asteroid Flyby mission is unlikely to be affected if it flies within the trail ahead of the comet in its orbit, but may collide with trail particles (having diameters of a few hundred microns) behind the comet.

Large scale structure of dust and gas in the Galaxy,ucture can be separated in velocity space using high resolution HI data. There is evidence for a correlation between the HI material at anomalous velocities, with wide profiles and the corresponding dust, showing higher 60/100 . flux ratios than the material at normal galactic velocities.

Individual Incentive Strategiesby stars with temperatures between 3,000 K and 21,000 K. The goal of this survey is a determination of the excitation of the small particles believed to be responsible for the 12 µm emission of these reflection nebulae.

The impact of IRAS on asteroidal science,e meteorite fields on the Antarctic ice cap. As expected, IRAS data on asteroidal albedos (the diameters and albedos of 1,811 asteroids have now been measured) will vastly extend the classification work. We anticipate that new insights into the chemical structure of the asteroid belt will be reveale

Iras observations of asteroids,own asteroids were also observed. There is an apparent difference in the albedo distribution of the asteroids as a function of size, however, this effect is probably an artifact due to a combination of factors such as faint source flux overestimation and confusion with faint background sources.
