Modelling complex organic molecules in dense regions: Eley–Rideal and complex induced reaction

摘要: Recent observations have revealed the existence of Complex Organic Molecules (COMs) in cold dense cores and prestellar cores. The presence these molecules such conditions is not well understood remains a matter debate since previously proposed "warm- up" scenario cannot explain observations. In this article, we study effect Eley- Rideal complex induced reaction mechanisms gas-phase carbon atoms with main ice components dust grains on formation COMs regions. Based recent experiments use low value for chemical desorption efficiency (which was invoked to observed COM abundances). We show that our introduced are efficient enough produce large amount organic at temperatures as 10K.
