International Research Fellow Awards: Accretion and Magnetism in Symbiotic Binary Stars

9902665Sokoloski国际研究员奖励计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项为联合研究以及使用国外独特或互补的设施、专业知识和实验条件提供了机会。该奖项将为Jennifer L.博士提供。Sokoloski与Phil A博士一起工作了12个月。查尔斯在英国牛津大学，并在哈佛大学剑桥，马萨诸塞州，与博士斯科特凯尼恩工作了12个月。 国家科学基金会的数学和物理科学理事会多学科活动办公室及其恒星天文学和天体物理学方案为该项目提供了部分支助，该项目涉及研究双星系统中物质的吸积，双星系统是白色矮星和红巨星的共生系统。 具体而言，这涉及使用X射线、紫外线和地面观测进行观测。 这些双星系统很重要，因为它们可能是超新星的祖先，而超新星又被用来在宇宙学尺度上计算距离。 首席研究员将可以使用英澳望远镜和加那利群岛望远镜的望远镜时间，以及波兰合作者提供的额外望远镜时间。 她还将测量双星系统的轨道大小，这是共生体从未完成过的。查尔斯博士是牛津大学天体物理学系的负责人，该系以其在相互作用双星领域的专业知识和广泛的研究兴趣而闻名。 斯科特·凯尼恩博士是共生双星的专家。

9902665SokoloskiThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide Dr. Jennifer L. Sokoloski with twelve months of support to work with Dr. Phil A. Charles at Oxford University in the UK, and for twelve months at Harvard University in Cambridge, MA, working with Dr. Scott Kenyon. Partial support for this project is provided by NSF's Directorate for Mathematical and Physical Sciences' Office of Multidisciplinary Activities and their Stellar Astronomy and Astrophysics Program.This project involves the study of the accretion of matter in binary systems, which are symbiotic systems of white dwarfs and red giants. Specifically, this involves observation using x-ray, ultraviolet and ground based observations. These binary systems are important because they might be progenitors of supernovae, which in turn are used to tabulate distances at cosmological scales. The principal investigator will have access to telescope time in the Anglo-Australian telescope and the telescope in the Canary Islands, with additional telescope time from collaborators in Poland. She will also be measuring the orbital size of the binary system, which has not ever been accomplished for symbiotics.Dr. Charles is the head of the astrophysics sub-department at Oxford, which is known for both expertise in the field of interacting binaries and breadth of research interests. Dr. Scott Kenyon is an expert on symbiotic binaries.***
