Theoretical Studies of Astronomical Masers

AST-0206149 PI Elitzur这个项目将继续进行一个广泛的，正在进行的天文脉泽理论研究计划。最近的微波激射干涉观测以前所未有的细节揭示了各种天文环境的结构。抓住这一进展所带来的机会，研究的主题包括：（1）水、一氧化硅和甲醇脉泽探测的大质量星星形成中的原恒星盘和外流;（2）各种脉泽和热物质追踪的演化恒星的星周壳;（3）OH脉泽推断的超新星遗迹对其环境的X射线和冲击影响;（4）氢氧脉泽探测的超新星遗迹对环境的影响;（5）氢氧脉泽探测的超新星遗迹对环境的影响;（6）氢氧脉泽探测的超新星遗迹对环境的影响;（7）氢氧脉泽探测的超新星遗迹对环境的影响;（8）氢氧脉泽探测的超新星遗迹对环境的影响;（9）氢氧脉泽探测的超新星遗迹对环境的影响;（10）氢氧脉泽探测的超新星遗迹对环境的影响;（10）氢氧脉泽探测的超新星遗迹对环境的影响。（4）OH和H_2O巨脉泽辐射揭示的星暴星系和活动星系核中心秒差距和亚秒差距尺度的结构。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密切合作。

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.***
