AST-0206149PI ElitzurThis project will continue a broad, ongoing program of theoretical studies of astronomical masers. Recent maser interferometric observations reveal in unprecedented detail the structure of various astronomical environments. Seizing the opportunities created by this progress, the topics targeted for research include (1) protostellar disks and outflows in high-mass star formation, as probed by water, SiO and methanol masers; (2) the circumstellar shells of evolved stars, traced by a variety of maser and thermalspecies; (3) the x-ray and shock impact of supernova remnants on their environment,deduced from OH masers; and (4) structure at the parsec and sub-parsec scales at the centers of starburst galaxies and active galactic nuclei as revealed by their OH and H2O mega-maser emission. In each case, a major ingredient of the theoretical research is the close collaboration with the teams conducting pertinent observations.***

AST-0206149PI Elitzur该项目将继续进行天文脉泽理论研究的广泛项目。最近的脉泽干涉观测以前所未有的细节揭示了各种天文环境的结构。抓住这一进展创造的机会，针对的研究课题包括：(1)由水、二氧化硅和甲醇脉泽探测的高质量恒星形成中的原恒星盘和流出；(2)由各种脉泽和热物种追踪的演化恒星的星周外壳；(3)超新星遗迹对其环境的X射线和冲击波影响，由OH脉泽推算；以及(4)从恒星爆发星系和活动星系核的OH和H2O巨脉泽发射揭示的在微秒和亚微秒尺度上的结构。在每一种情况下，理论研究的一个主要组成部分是与进行相关观察的团队的密切合作。
