LABORATORY INVESTIGATION OF X-RAY PHOTOLYSIS OF ETHANOL ICE AND ITS IMPLICATION ON ASTROPHYSICAL ENVIRONMENTS

Autor: Sergio Pilling, Fabricio M. Freitas

Publikováno v: Revista UniVap, Vol 29, Iss 61 (2023)

Here we present experimental results on the irradiation of ethanol ice (CH3CH2OH) by broadband soft X-rays to simulate the effect processing of organic-rich astrophysical ices by space radiation. This molecule was detected in the interstellar medium

Spectroscopic Constants and Anharmonic Vibrational Frequencies of C(O)OC, c-C2O2 and Their Silicon-Containing Analogues

Autor: Fortenberry, Olivia A. Harwick, Ryan C.

Publikováno v: Molecules; Volume 28; Issue 11; Pages: 4563

Comets are likely to contain various carbon oxide molecules potentially including C(O)OC and c-C2O2 on their surfaces and comae, as well as their silicon-substituted analogues possibly playing a role in the formation of interstellar dust grains. In t

Several nitrogen-containing molecules have been unambiguously identified in the Solar System and in the Interstellar Medium. It is believed that such a rich inventory of species is a result of the energetic processing of astrophysical ices during the
