    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...

    The Chemistry of the First Stars-Carbon in the Early Universe
    The very metal-poor (VMP; [Fe/H] < –2.0) and extremely metal-poor (EMP; [Fe/H] < –3.0) stars provide a direct view of Galactic chemical and dynamical evolution...

    The chemistry of the last major merger
    One prediction of ΛCDM is the existence of partially phase-mixed substructures from accreted dwarf galaxies in the Milky Way stellar halo. Substructure...

    The complex Milky Way history
    In this seminar I will focus on how the avalanche of new data changes our views on how our Galaxy formed and evolved. Precise astrometric, spectroscopic...

    The Formation of Fullerenes: Clues from New C60, C70, and (Possible) Planar C24 Detections in Magellanic Cloud Planetary Nebulae
    We present 10 new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule...

    The last asymptotic giant branch star
    All the elements from carbon to uranium present in the Solar System were produced by hundreds to thousands of stars belonging to different stellar generations...
