项目摘要

Planets and stars form at the same time in warm, dusty disks surrounding the stars. Using 80 hours of observing time on the 8-meter telescope Gemini South in Chile with the Gemini Planet Imager instrument, these investigators will image the structure in a dust disk with very high resolution. As planets form and grow, disks develop spiral arms, gaps, and eventually hollow cavities -- signposts of planet formation. The investigators will study a sample of 30 dust disks covering all stages of the formation of planets. They will follow-up with telescopic instruments covering other observable traits of the stars and disks. The basic stages of planet formation can be determined structurally within the dust disks around the sample stars. This project supports the mission of the NSF by promoting our understanding of the stages of planet formation within dust disks around other stars. The lead investigator will continue his partnership with the Ann Arbor Hands-on Museum to reach out to the often-overlooked rural population of Michigan through traveling astronomical science exhibits.The Gemini Planet Imager (GPI) instrument can image dust structure with spatial resolution as small as 6 AU by exploiting extreme adaptive optics, coronagraphy, and a differential polarization mode. The proposed observational survey of 30 disks draws evenly from a sample of intermediate-mass young stellar objects spanning all the known stages of planet formation. Follow-up using the mm-wave and other visible/IR high-contrast instruments will be pursued as part of the proposed research plan. By linking newly discovered disk structures with stellar ages, spectral types, and the disk spectral energy distributions for a statistically-significant number of objects, the fundamental stages of planet formation can be determined both morphologically and then quantitatively through the proposed radiative transfer and hydrodynamical modeling to estimate disk masses, disk scale heights, dust sizes, and the radii of gaps and other structures.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.

行星和恒星同时在恒星周围的温暖，尘土飞扬的磁盘中形成。这些研究人员使用Gemini Planet Imager仪器在智利的8米望远镜Gemini South上进行观察时间，这些研究人员将在灰尘磁盘中以非常高的分辨率进行成像。随着行星形成并成长，磁盘会形成螺旋臂，缝隙，最终形成空心腔 - 行星形成的路标。研究人员将研究一个涵盖行星形成的所有阶段的30个防尘盘的样本。他们将跟进覆盖其他可观察到的恒星和磁盘特征的望远镜仪器。行星形成的基本阶段可以在样品恒星周围的灰尘磁盘中结构确定。该项目通过促进我们对其他恒星周围尘埃中行星形成阶段的理解来支持NSF的使命。首席调查员将继续与安阿伯动手博物馆（Ann Arbor）的合作伙伴关系，通过旅行天文学科学展览与经常被忽视的密歇根州的农村人口接触。GeminiPlanet Imager（GPI）仪器可以通过在空间分辨率下图像尘埃结构，并通过在空间分辨率上进行尘埃结构，从而通过高达6 AU的空间分辨率来利用极端自适应的光学，coronagragragragraphy和Adys Adysial polaraphy and Adlactial polarsigation and Adection。提出的对30个磁盘的观察性调查均匀地从中间质量的年轻恒星物体样本中均匀地绘制，这些样本涵盖了行星形成的所有已知阶段。使用MM波和其他可见/IR高对比度仪器的后续措施将作为拟议的研究计划的一部分进行。 By linking newly discovered disk structures with stellar ages, spectral types, and the disk spectral energy distributions for a statistically-significant number of objects, the fundamental stages of planet formation can be determined both morphologically and then quantitatively through the proposed radiative transfer and hydrodynamical modeling to estimate disk masses, disk scale heights, dust sizes, and the radii of gaps and other structures.This award反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准来评估值得支持。
