3.4 and 10 μm emission from comet Halley dust - further evidence for interstellar dust with silicate cores and organic refractory mantles.
Abstract
The 3.4 μm emission of comet Halley is used to calculate the temperature of the dust. The dust temperature is higher than that of the comet. The production rate of dust was 1.1×106g s-1 on 28 March 1986. The dust-to-gas ratio was 0.1 for the emitting particles alone. The properties of the dust are shown to follow from the adopted interstellar dust model.
