Issue Date: | 2020 | Volume: | Laboratory Astrophysics: From Observations to Interpretation | Editors: | Salama, Farid; Linnartz, Harold | Series: | PROCEEDINGS OF THE INTERNATIONAL ASTRONOMICAL UNION | Number: | vol.15, S350 | First Page: | 109 | Abstract: | We present the results of an experimental study on the interaction of D atoms with Mg-rich amorphous silicates. The effects of D irradiation have been analyzed by infrared spectroscopy. The results indicate that HD forms by abstraction of hydrogen atoms chemisorbed in the hydroxyl groups of silicate grains. The formation process occurs for grain and atom temperatures relevant to photodissociation regions. | Conference Name: | Laboratory Astrophysics: From Observations to Interpretation | Conference Place: | Cambridge | Conference Date: | 14-19 April, 2019 | URI: | http://hdl.handle.net/20.500.12386/31656 | URL: | https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/issue/7AA4A73FABCBFF4BD0D9E2CFD327926C https://api.elsevier.com/content/abstract/scopus_id/85094854509 |
