    Characterization of Cosmic Materials in the Laboratory

    One of the main objectives of modern astrophysics is the characterisation of properties and evolution of materials present in space. Production, processing and analysis of cosmic dust analogues in the laborato...

    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...

    Laboratory Spectra of Amorphous and Crystalline Olivine: An Application to Comet Halley IR Spectrum

    Among the various silicates proposed as components of cosmic dust grains, olivine is considered one of the most likely materials. In this work we present the infrared spectra of three different types of olivin...

    Simulation in Laboratory of Solid Grains Present in Space

    Laboratory data on cosmic dust analogue materials are compared with recent results obtained by means of spectroscopy and mass spectrometry on cometary dust, meteorites and interplanetary dust. Their actual che...

    Optical Properties of Carbonaceous Materials

    We discuss the optical properties of carbonaceous materials from the VUV to the FIR. Updated laboratory data on amorphous carbon (HAC) and some PAH mixtures are analysed and compared with relevant literature. ...

    Physical Properties of Submicronic Carbonaceous Particles Candidate as Cosmic Dust

    We present here a compendium of our laboratory measurements of the physical properties of submicronic particles made by some carbonaceous materials candidate as cosmic dust: amorphous carbon, silicon carbide. ...
