Astrochemistry: February 2019

In the laboratory, the photo-and thermochemical evolution of ices, made of simple molecules of astrophysical relevance, always leads to the formation of semi-refractory water-soluble organic residues.

We report a computational study of the stability and infrared (IR) vibrational spectra of neutral and singly ionised fullerene cages containing between 44 and 70 carbon atoms.

Young stars are often surrounded by a protoplanetary disk where planets are forming. Astronomers study the composition of protoplanetary disks to better understand how planets, like Earth, formed and evolved into their modern chemical composition.

Protoplanetary disks are dust-rich structures around young stars. The crystalline and amorphous materials contained within these disks are variably thermally processed and accreted to make bodies of a wide range of sizes and compositions, depending on the heliocentric distance of formation.
