    UV Irradiation of Small Carbon Grains

    We present preliminary results of an experiment aimed at simulating the UV processing of hydrogenated amorphous carbon grains occurring in the interstellar medium. UV exposure of these grains induces significa...

    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...

    The Infrared Characteristics of Circumstellar Silicate Grains

    We have made a theoretical study of the infrared emission from circumstellar shells around late-type giants, with the aim of deriving the infrared characteristics of the silicate grains condensing in these she...
