报告题目:Modeling Studies of Interstellar Prebiotic Molecules

报告 人:全冬晖(新疆天文台)

摘要:Despite the extremely low density and the relatively low temperature of interstellar medium, over 140 molecules, including many organic ones, have been observed towards various sources. Several of the detected interstellar molecules are named prebiotic molecules since they can easily form biological molecules such as amino acids. Here I present recent studies of the chemistry of these prebiotic molecules using models which are based on chemical kinetics rate equations. To simulate the complex physical environment of the astronomical resources where the prebiotic molecules were detected, we have built a serial of models, including the cold, warm-up, and shock models. Calculated fractional abundances are compared with the observed values and the formation and destruction mechanism of these prebiotic molecules, as well as the physical conditions of the regions where they were detected, are identified by the models.
