The vibrational properties of benzene on an ordered water ice surface (2021)
Journal Article
Clark, V. H., & Benoit, D. M. (2021). The vibrational properties of benzene on an ordered water ice surface. Monthly notices of the Royal Astronomical Society, 508(3), 3239-3250. https://doi.org/10.1093/mnras/stab2670We present a hybrid CCSD(T) + PBE-D3 approach to calculating the vibrational signatures for gas-phase benzene and benzene adsorbed on an ordered water ice surface. We compare the results of our method against experimentally recorded spectra and calcu... Read More about The vibrational properties of benzene on an ordered water ice surface.
The Gaia-ESO Survey: A new approach to chemically characterising young open clusters (2021)
Journal Article
Baratella, M., D'Orazi, V., Sheminova, V., Spina, L., Carraro, G., Gratton, R., …Zaggia, S. (2021). The Gaia-ESO Survey: A new approach to chemically characterising young open clusters. Astronomy and Astrophysics, 653, Article A67. https://doi.org/10.1051/0004-6361/202141069Context. Young open clusters (ages of less than 200 Myr) have been observed to exhibit several peculiarities in their chemical compositions. These anomalies include a slightly sub-solar iron content, super-solar abundances of some atomic species (e.g...

This prediction questions t... Read More about Evaluation of the N 13 (α,p) O 16 thermonuclear reaction rate and its impact on the isotopic composition of supernova grains.
