Context. Nonthermal desorption from interstellar ices induced by X-rays, known as X-ray photodesorption, is a possible route to explain gas phase molecules detected in protoplanetary disks. However, the efficiency of […]

Chandra X-ray Observatory Checks The Habitability Of Exoplanets
Using NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy […]

X-ray Photodesorption Of Complex Organic Molecules In Protoplanetary Disks — I. Acetonitrile CH3CN
X-rays emitted from pre-main-sequence stars at the center of protoplanetary disks can induce nonthermal desorption from interstellar ices populating the cold regions. This X-ray photodesorption needs to be quantified for […]
