Submillimeter Interferometry of the Orion Proplyds

AST-0607710机构：夏威夷大学PI：Jonathan Williams标题：猎户座探测器的亚毫米干涉测量。夏威夷大学的乔纳森威廉姆斯将进行一项计划，用亚毫米阵列对猎户座梯形星团中的星周盘样本进行成像。 研究的目的包括：1）比较梯形和金牛座的盘质量分布; 2）测量梯形内盘质量作为半径的函数; 3）限制这些盘内的颗粒性质; 4）评估接近大质量恒星对盘演化的影响; 5）分辨最大的圆盘并测量这些系统的动力学质量。这项工作的更广泛的影响将主要是亚毫米天文学和干涉测量学研究生的教育和培训。 一名本科生也将参加该项目。 这项调查及其对行星形成的影响，可能与我们自己的太阳系相似，也将引起公众的普遍兴趣。 威廉姆斯博士将把研究结果和方法纳入夏威夷大学的课程中。

AST-0607710INSTITUTION: University of HawaiiPI: Jonathan WilliamsTITLE: Submillimeter Interferometry of the Orion Proplyds ABSTRACTDr. Jonathan Williams, at the University of Hawaii, will undertake a program to image a sample of circumstellar disks in the Trapezium Cluster in Orion with the SubMillimeter Array. Among the goals of the research are: 1) to compare the disk mass distribution in the Trapezium to that in Taurus; 2) to measure disk masses as a function of radius within the Trapezium; 3) to constrain the grain properties within these disks; 4) to assess the impact of proximity to massive stars on disk evolution; and 5) to resolve the largest disks and measure dynamical masses of these systems.The broader impact of this work will predominantly be the education and training of a graduate student in submillimeter astronomy and interferometry. An undergraduate student will also participate in the project. The survey, with its implications for planet formation in conditions that may have been similar to that of our own solar system, will also be of general public interest. Dr. Williams will incorporate the research results and methodology into classes at the University of Hawaii.
