论文标题：BETTII：远红外极大值恒星形成区高角度分辨率观测的探路者哲学博士J·里佐，2016年博士论文由：天文学系Lee Mundy教授和NASA GSFC Stephen Rinehart博士指导。在这篇论文中，我们研究了近红外星团中的星团恒星形成，并讨论了远红外区的高角度分辨率观测如何帮助我们理解这些重要的恒星诞生区域。我们利用索非亚航空天文台上的FORCAST仪器增加的角分辨率研究了附近的10个恒星形成区，并讨论了这些地区的源的物理性质，我们可以利用这些新的观测数据从辐射传输模拟中推断出这些源的物理性质。我们讨论了BETTII的设计，这是一种探路器气球载干涉仪，将在远红外区域提供显著更好的角分辨率，并为未来的空间观测站铺平道路。我们详细阐述了BETTII的核心技术，即双傅立叶干涉测量，以及如何准确地计算使用该技术的仪器的灵敏度。最后，我们给出了BETTII有效载荷控制和姿态估计系统的设计和实现结果，这对气球平台上的干涉仪提出了独特的挑战。BETTII：远红外恒星形成区高角分辨率观测的探路器
Title of dissertation: BETTII: A PATHFINDER FOR HIGH ANGULAR RESOLUTION OBSERVATIONS OF STAR-FORMING REGIONS IN THE FAR-INFRARED Maxime J. Rizzo, Doctor of Philosophy, 2016 Dissertation directed by: Professor Lee Mundy, Department of Astronomy and Dr. Stephen Rinehart, NASA GSFC In this thesis, we study clustered star formation in nearby star clusters and discuss how high angular resolution observations in the far-infrared regime could help us understand these important regions of stellar birth. We use the increased angular resolution from the FORCAST instrument on the SOFIA airborne observatory to study 10 nearby star-forming regions, and discuss the physical properties of sources in these regions that we can infer from radiative transfer modeling using these new observations. We discuss the design of BETTII, a pathfinder balloon-borne interferometer which will provide significantly better angular resolution in the far-infrared regime, and pave the way for future space-borne observatories. We elaborate on the details of BETTII’s core technique, called Double-Fourier interferometry, and how to accurately compute the sensitivity of instruments which use this technique. Finally, we show our design and implementation results of the control and attitude estimation system for the BETTII payload, which poses unique challenges as an interferometer on a balloon platform.
