    A Catalog of Diffuse Interstellar Bands in Fullerene-Containing Planetary Nebulae
    Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common...

    A search for hydrogenated fullerenes in fullerene-containing planetary nebulae
    Detections of C60 and C70 fullerenes in planetary nebulae (PNe) of the Magellanic Clouds and of our own Galaxy have raised the idea that other forms of carbon...

    Airglow in the atmospheres of the terrestrial planets
    There is a multitude of photochemical processes occurring in a planet's atmosphere. Some of these processes occur with an excess of energy and lead to products...

    Amino acids in comets and meteorites: stability under gamma radiation and preservation of the enantiomeric excess
    Amino acids in Solar system bodies may have played a key role in the chemistry that led to the origin of life on Earth. We present laboratory studies testing...
