    On the interpolation of model atmospheres and high-resolution synthetic stellar spectra
    We present tests carried out on optical and infrared stellar spectra to evaluate the accuracy of different types of interpolation. Both model atmospheres and...

    On the Presence of Metallofullerenes in Fullerene-rich Circumstellar Envelopes
    The presence of neutral C 60 fullerenes in circumstellar environments has been firmly established by astronomical observations as well as laboratory experiments...

    Organic materials and ices in the outer solar system
    The composition of the outer solar system is of particular interest because it holds the key to understanding the chemical evolution of the Solar System...

    Origin of two primitive NEAs: (3200) Phaethon and 1998 RQ36
    Understanding the composition and the nature of any asteroid approaching the Earth, and consequently potentially hazardous, is a matter of general interest...

    Spectroscopy of Fullerenes, Fulleranes and PAHs in the UV, Visible and Near Infrared Spectral Range
    The spectra of fullerenes C60 and C70, higher fullerenes C76, C78 and C84 and hydrogenated fullerenes (fulleranes) were studied in laboratory in the UV and in...
  • Publication
    Stability of C60 and C70 fullerenes toward corpuscular and γ radiation
    The stability of C60 and C70 fullerenes in the interstellar medium deposited on dust surface or embedded in meteorites and comets has been simulated with γ...

    Stellar black holes at the dawn of the Universe: cosmological implications
    The so called "dark ages" of the universe began about 400.000 years after the Big Bang as matter cooled down and space became filled with neutral hydrogen for...

    Temperature inhomogeneities cause the abundance discrepancy in H II regions
    H II regions, ionized nebulae associated to massive star formation, exhibit a wealth of emission lines that are the fundamental basis for estimating the...

    The 2008 Outburst of EX Lup—Silicate Crystals in Motion
    EX Lup is the prototype of the EXor class of eruptive young stars. These objects show optical outbursts which are thought to be related to runaway accretion...
