Theoretical Studies of Astronomical Masers

这个项目将继续一个广泛的、正在进行的天文脉泽理论研究项目。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。抓住这一进展所创造的机会，目标研究课题包括：(1)由水、SiO和甲醇微波激射器探测的大质量恒星形成中的原恒星盘和流出物；(2)演化恒星的星周壳，由各种脉泽和热源追踪；(3)超新星遗迹对周围环境的x射线和激波影响，由OH脉泽推断；(4)星暴星系和活动星系核中心的秒差距和亚秒差距尺度的结构，这是由它们的OH和H2O巨型脉泽发射所揭示的。在每种情况下，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.***
