Comet Halley as an aggregate of interstellar dust and further evidence for the photochemical formation of organics in the interstellar medium
Photolysis of mixtures of CO:NH3:H2O at 12 K results in the formation of an organic residue which is not volatile in high vacuum at room temperature. Analysis of this fraction by GC-MS resulted in the detection o...

Formation of Organic Molecules on Interstellar Dust Particles
The 3.4 um absorption feature in the spectrum of several infrared sources (Wickramasinghe and Allen, 1981; Willner and Pipher, 1982) indicates the presence of organic molecules in the interstellar medium. Seve...
