What Does High-Mass Star Formation "Look" Like? Movies Of Accretion And Outflow 10 - 1000 AU From A Massive YSO

介绍：史密森学会天体物理天文台PI：伊丽莎白·汉弗莱斯：大质量恒星的形成是什么样子的？从一个巨大的YSO吸收和流出10-1000 AU的电影。史密森学会天体物理天文台的伊丽莎白·汉弗莱斯将与国家射电天文台的共同研究员克莱尔·钱德勒和SAO的林肯·格林希尔一起开展一项计划，直接绘制和跟踪猎户座KL区域一个深埋的大质量年轻恒星物体(YSO)周围的气体三维动力学。要研究的区域在距源头10到1000个天文单位的半径处，物质从吸积盘中流出。这个源是已知的最近的大规模YSO，也是唯一可以进行这类研究的目标。研究计划的成果将是一部明星形成的电影，这将成为CD-ROM和基于网络的教育计划的基石。该项目将与圣保罗科学教育局共同开发，通过向学校、天文馆和博物馆传播，面向学生和普通公众。此外，校准后的数据和图像将存储在一个可公开访问的网络档案中，预计本科生将参与这项研究。

AST-0507478INSTITUTION: Smithsonian Institution Astrophysical ObservatoryPI: Elizabeth HumphreysTITLE: What Does High-Mass Star Formation "Look" Like? Movies Of Accretion And Outflow 10 - 1000 AU From A Massive YSO ABSTRACTDr. Elizabeth Humphreys, at the Smithsonian Institution Astrophysical Observatory (SAO), along with co-investigators Claire Chandler at the National Radio Astronomy Observatory and Lincoln Greenhill at the SAO, will undertake a program to directly map and track the 3-D dynamics of gas around a massive, a deeply embedded young stellar object (YSO) in the Orion KL region (radio source "I"). The region to be studied is at radii of 10 to 1000 Astronomical Units from the source, where outflow of material is launched from an accretion disk. The source is the closest known massive YSO, and the only target for which this type of study can be undertaken. An outcome of the research program will be a movie of a star in formation, which will serve as the cornerstone of a CD-ROM and web-based education program. The program will be developed with the SAO Science Education Department, and will be directed toward students and the general public through dissemination to schools, planetaria and museums. Additionally, calibrated data and images will be stored in a publicly accessible web archive, and undergraduate student involvement in the research is anticipated.
