    New Advances in Nebular Spectroscopy of Heavy Elements
    The origins of neutron(n)-capture elements (atomic number Z > 30) have historically been discerned from the interpretation of stellar spectra. However, in the...

    On the action of UV photons on hydrogenated fulleranes C60H36 and C60D36
    Fulleranes, the hydrogenated fullerenes C60H36 and C60D36 have been synthesized in n-hexane where they show an absorption maximum at 217 nm in their electronic...

    On the alumina dust production in the winds of O-rich asymptotic giant branch stars
    The O-rich asymptotic giant branch (AGB) stars experience strong mass-loss with efficient dust condensation and they are major sources of dust in the...

    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...
