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.

机构：史密森学会天体物理观测台i: Elizabeth HumphreysTITLE：高质量恒星形成“看起来”像什么？大质量YSO的吸积和流出电影[j]。史密森学会天体物理天文台（SAO）的伊丽莎白·汉弗莱斯（Elizabeth Humphreys）将与国家射电天文台的共同研究员克莱尔·钱德勒（Claire Chandler）和SAO的林肯·格林希尔（Lincoln Greenhill）一起，开展一项计划，直接绘制和跟踪猎户座KL区域（射电源“I”）中一个巨大的深嵌年轻恒星物体（YSO）周围气体的三维动力学。要研究的区域距离源的半径为10到1000天文单位，在那里物质从吸积盘流出。该源是已知最接近的大质量YSO，也是可以进行此类研究的唯一目标。该研究项目的成果将是制作明星信息电影，并作为光盘和网络教育项目的基础。该计划将与SAO科学教育部门共同制定，并将通过在学校、天文馆和博物馆的宣传，面向学生和公众。此外，校准的数据和图像将存储在一个可公开访问的网络档案中，并且预计本科生将参与研究。
