We present observations of the full Stokes vector in a flaring region, taken in the chromospheric He I 10830 Å multiplet. The data were recorded with the new...

The detections of fullerenes and (possibly) planar C_{24} (a small fragment of a graphene sheet) in the H-rich circumstellar environments of evolved stars show...

The most prominent feature in the interestellar medium extinction curve is the UV bump at 217.5 nm. The carrier of this band has been frequently associated to...

We have studied the contribution of single fullerenes and buckyonions to the interstellar extinction. The photoabsorption spectra of these molecules is...

Fullerenes, highly resistant and stable tridimensional carbon molecules, have attracted much attention since their discovery at laboratory by Kroto and...

Theoretical, observational and laboratory work on the new form of carbon known as fullerenes and its hydrogenated forms (fulleranes) are reviewed. These...

We will review theoretical, experimental and observational work on the new form of carbon known as fullerenes and its hydrogenated forms (fulleranes). This type...

According to semiempirical models, photoabsorption by fullerenes (single and multishell) could explain the shape, width and peak energy of the most prominent...

The discovery potential from astronomical and other data is limited by their noise. We introduce a novel non-parametric noise reduction technique based on...
