The Intriguing Behavior of Ultraviolet Photodesorption and Color Temperature of Astrophysical CO Ice Analogs: A Possible Indication of Molecular Disorder

發佈於 分類: PPS2021

Ejection of molecules from ice-covered dust exposed to ultraviolet photons, known as photodesorption, is summoned to account for gas abundances in cold regions. Carbon monoxide (CO) is the second most abundant ice component in interstellar clouds. Photon energy transfer between CO molecules can eventually excite molecules on the ice surface, allowing desorption. CO photodesorption drops […]
