TalkNew 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...

PublicationOn 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...

PublicationOn 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...

PublicationOn 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...
