Disks surrounding massive stars

在可观测的宇宙中，盘结构无处不在。星系在其圆盘的旋臂上产生新的恒星，行星通过恒星形成遗留下来的类圆盘物质形成，黑洞与圆盘联系在一起。在年轻和年老的恒星周围以及双星系统中也发现了圆盘。目前，我的研究重点是与大质量恒星相关的盘状物质，以了解盘状物质的形成过程以及这些系统对周围环境的影响。大质量恒星是风和电离辐射的重要来源，影响其周围环境，并塑造其母星系的演化。 我使用详细的计算机模型来预测可观测性，如谱线、偏振和光谱能量分布，以便与许多不同来源的观测数据进行比较，这些来源包括干涉仪、卫星和地面观测站在广泛的波长范围内。这些详细的比较对模型输入参数施加了严格的约束，并允许确定星/盘系统中的物理条件。 最终，我关于大质量恒星周围的圆盘的发现可能会扩展到我们对其他类似圆盘的分布的理解上。我使用新的观测技术，特别是高分辨率干涉测量，再加上增加的计算机能力和数据存储，将使我能够在扩大我们对这些盘状区域的知识方面取得重大进展。

Disk structures are ubiquitous within the observable universe. Galaxies produce new stars in the spiral arms of their disks, planets form through the disk-like material left over from star formation, and black holes are associated with disks. Disks are also found around young and old stars as well as in binary systems. Currently, my research focuses on disk material associated with massive stars in order to understand the process of disk formation and the influence that these systems have on their surroundings. Massive stars are an important source of both winds and ionizing radiation that affect their immediate environment as well as shape the evolution of their parent galaxy. I use detailed computer models to predict observables such as spectral lines, polarization, and spectral energy distributions for comparison with observational data from many different sources including interferometers, satellites and ground-based observatories over a wide range of wavelengths. These detailed comparisons place tight constraints on model input parameters and allow the physical conditions in the star/disk system to be determined. Ultimately, my findings regarding disks surrounding massive stars may be extended to further our understanding of other disk-like distributions. My use of new observational technologies, especially high-resolution interferometry, combined with increased computer capabilities and data storage, will allow me to make significant progress in expanding our knowledge of these disk-like regions.
