Constraining Planet Formation Around Hundreds of Young Stars in Rich Clusters

星星和行星的形成是同时发生的，在银河系的区域不到1000万年。 银河系中的大多数恒星都形成密集的恒星群或星团。这项研究将产生迄今为止最全面和最详细的研究，研究有可能在这些典型的密集恒星形成区域形成围绕恒星的行星。 在以前资助的工作中，研究人员获得了这个新项目的基本数据，并在科学期刊上发表了第一批结果。 在这里，研究人员将联合收割机将这些数据与其他科学家提供的支持数据结合起来，增加新望远镜观测结果的数据量，并分析所有数据。这些结果将限制行星、尘埃盘和成团星星形成的理论模型。 该项目通过促进我们对密集的、聚集的星星形成区域中行星形成盘的形成的理解来支持NSF的使命。首席研究员将在研究项目中包括一名来自非传统背景的学生，并将通过他所教授的课程和公开的晚间讲座分享研究结果。这项研究将产生迄今为止对集群星星形成区域中潜在行星形成盘的最全面和最高角分辨率的研究。 这种密集的、短暂的、短暂的星团包含100到1000多颗正在形成的恒星，这些恒星位于巨大的分子云内的自引力、秒差距直径的团块中，外流反馈、紫外线辐射、恒星风和超新星塑造了行星形成的环境。 预期的结果将包括数百个同时代原行星盘的行星形成区内的星周质量，这些盘的尺寸分布，对其他盘参数的约束，如刻度高度和表面密度分布，以及盘，恒星，该奖项反映了NSF的法定使命，并被认为是值得通过评估使用基金会的知识产权的支持。优点和更广泛的影响审查标准。

Star and planet formation occur at the same time, in regions of the Galaxy less than about 10 million years old. Most stars in the Galaxy form in dense groups or clusters. This research will produce the most comprehensive and detailed study to date of the dust disks with the potential to form planets surrounding stars in these typical, dense star-forming regions. In previously-funded work, the investigator obtained the basic data for this new program and published the first results in scientific journals. Here, the investigators will combine these data with available supporting data from other scientists, increase the amount of data with the results from new telescopic observations, and analyze all of the data. These results will constrain theoretical models of planet, dust disk, and clustered star formation. This project supports the mission of the NSF by promoting our understanding of the formation of planet-forming disks in dense, clustered star forming regions. The lead investigator will include a student from a non-traditional background in the research project, and will share the research results with classes that he teaches and through public evening lectures.This research will produce the most comprehensive and highest angular resolution study to date of potentially planet-forming disks in clustered star forming regions. Such dense, transient, short-lived clusters contain from 100 to over 1000 forming stars inside self-gravitating, parsec diameter clumps within giant molecular clouds where outflow feedback, UV radiation, stellar winds, and supernovae shape the environment of planet formation. The expected results will include the circumstellar masses within the planet-forming zones of hundreds of coeval protoplanetary disks, the size distribution for these disks, constraints on other disk parameters such as scale height and surface density profile, and relationships between disk, stellar, and environmental properties.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
