Complex molecules in the Orion Kleinmann-Low nebula

摘要

In the framework of the delivery to the early Earth of extraterrestrial molecules, we have studied complex molecular species toward the Orion Kleinmann-Low nebula. This nebula is rich in molecules as well as in nascent stars and planetary systems. We focus here on HCOOCH_3, CH_3OCH_3 and deuterated methanol. Upper limits on species of prebiotic interest like glycine were also obtained.
