Ethanolamine (NH _2 CH _2 CH _2 OH) has recently been identified in the molecular cloud G+0.693-0.027, situated in the SgrB2 complex in the Galactic center. However, its presence in other regions, and in particular in star-forming sites, is still elu

Icy mantles of benzonitrile, an aromatic with a cyanide side chain that has recently been detected in the interstellar medium, were subjected to vacuum ultraviolet photon irradiation and found to form a residue. The residue was removed from the subst

The astrochemistry of CO2 ice analogues has been a topic of intensive investigation due to the prevalence of CO2 throughout the interstellar medium and the Solar System, as well as the possibility of it acting as a carbon feedstock for the synthesis

Vacuum ultraviolet photoabsorption of prime ice analogues of Pluto and Charon

Autor: B.-M. Cheng, Nigel J. Mason, B. N. Raja Sekhar, S Pavithraa, Bhalamurugan Sivaraman, J.-I. Lo, K.K. Rahul

Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 190:172-176

Here we present the first Vacuum UltraViolet (VUV) photoabsorption spectra of ice analogues of Pluto and Charon ice mixtures. For Pluto the ice analogue is an icy mixture containing nitrogen (N2), carbon monoxide (CO), methane (CH4) and water (H2O) p
