Imaging Planet-Forming Disks and Stellar Surfaces: An Integrated Program of New Observations and Algorithm Development

研究人员将使用查拉干涉仪来观察和分析年轻恒星物体周围行星形成盘的内部区域。他们的工作将测试吸积原行星、恒星表面、年轻恒星天体的光谱可变性以及非轴原行星盘对称性的模型。作为分析的一部分，他们将利用压缩传感理论开发关键的成像软件，用于图像重建和数据分析。这项工作具有重大的更广泛的影响，因为用于图像重建的算法将向公众开放，也适用于使用其他仪器获得的天文干涉数据，包括那些在其他波长制度(如无线电)下工作的仪器，并可能被社区中的许多天文学家使用。

The investigators will use the CHARA Interferometer to observe and analyze the inner regions of planet-forming disks around Young Stellar Objects. Their work will test models of accreting protoplanets, stellar surfaces, spectral variability of Young Stellar Objects, and non-axis protoplanetary disk symmetries. As part of the analysis, they will develop critical imaging software using Compressed Sensing Theory for image reconstruction and analysis of the data. The work has significant broader impacts in that the algorithms used for image reconstruction will be publicly available and also applicable to astronomical interferometric data obtained with other instruments, including those working at other wavelength regimes (such as radio), and may be used by many astronomers in the community.
