Evolutionary Chemical - Dynamical Models of Interstellar Clouds

9413242普拉萨德博士将通过进化的化学动力学模型阐明观测到的星际云的分子组成。与大多数以前假定固定物理条件的平衡化学模型不同，所提出的模型将考虑化学和动力学之间的基本相互作用。预计新的模型可以更好地阐明：(1)给定的云可以达到其当前状态的过程；(2)它将如何随时间进一步演变；以及(3)当前静态的伪时间相关的气相化学模型所面临的日益增长的困难。该奖项是根据美国国家科学基金会的探索性研究小额赠款计划颁发的。

9413242 Prasad Dr. Prasad will elucidate the observed molecular composition of interstellar clouds through evolutionary chemical-dynamical models. In contrast to most previous equilibrium chemical models which assume fixed physical conditions, the proposed models will account for the fundamental interaction between the chemistry and dynamics. It is expected that the new models can better clarify: (1) The processes by which a given cloud can attain its present state; (2) how it will further evolve with time, and (3) the growing difficulties that are confronting current static pseudo-time-dependent gas phase chemical models.
