Many complex organic molecules and inorganic solid-state compounds have been observed in the circumstellar shell of stars (both C-rich and O-rich) in the...
NanoSpace: Networking as a tool to understand carbon molecular nanostructures in planetary nebulae
I present a short overview of the COST Action NanoSpace ("Carbon molecular nanostructures in space"; CA21126) together with the most recent updates. This...
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...
New ATLAS9 and MARCS Model Atmosphere Grids for the Apache Point Observatory Galactic Evolution Experiment (APOGEE)
We present a new grid of model photospheres for the SDSS-III/APOGEE survey of stellar populations of the Galaxy, calculated using the ATLAS9 and MARCS codes...
New H-band Stellar Spectral Libraries for the SDSS-III/APOGEE Survey
The Sloan Digital Sky Survey-III (SDSS-III) Apache Point Observatory Galactic Evolution Experiment (APOGEE) has obtained high-resolution (R ∼ 22,500), high...
Nonequilibrium CO Chemistry in the Solar Atmosphere
Investigating the reliability of the assumption of instantaneous chemical equilibrium (ICE) for calculating the CO number density in the solar atmosphere is of...
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...
