Theoretical Studies and Interstellar Matter. Dr. Dalgarno will direct theoretical studies of photon-dominated regions of interstellar matter, incorporating the photodestruction of molecular ions. The ionization structure of such regions will be calculated. The photodissociation of molecular nitrogen will be included in a study of nitrogen chemistry. Regions subjected to intense X-ray fluxes will be investigated, and the infrared response of molecular hydrogen will be obtained. The thermal and chemical structure of supernova remnant SN 1987A will be investigated. Calculations of charge transfer of ionized helium will be performed.

理论研究与星际物质。达尔加诺博士将指导星际物质中以光子为主的区域的理论研究，包括分子离子的光破坏。这些区域的电离结构将被计算出来。分子氮的光解离将包括在氮化学的研究中。我们将研究受到强X射线通量影响的区域，并获得分子氢的红外响应。超新星遗迹SN1987A的热结构和化学结构将被研究。将对电离氦的电荷转移进行计算。
