AST-0302055Sokoloski, JenniferDr. Sokoloski is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the Harvard-Smithsonian Center for Astrophysics. She will address the creation of astrophysical jets, which are found on many different size scales in the universe. The cause of these highly focused outflows are thought to be accretion disks around central objects, but are not well understood. Dr. Sokoloski will conduct a detailed study of accretion disks around symbiotic stars, in which a white dwarf star accretes gas from the stellar wind of a red giant. The three facets of the research project will be (1) an archival spectroscopic survey for jets in symbiotic stars, plus complementary radio, optical, and X-ray imaging observations; (2) an exploration of the disk-jet connection in symbiotic stars, including interferometric observations that could possibly produce the first image of a tidally distorted star; and (3) a detailed examination of the jet-producing inner-disk region in selected white-dwarf accretors. The goal is to use the symbiotic stars to distinguish between competing jet models, both for these systems and for astrophysical jets generally. Dr. Sokoloski will also work towards increasing the participation of women and girls in science. She will continue to participate in the "Eyes to the Future" science mentorship program for middle-school girls, and focus on recruiting colleagues to participate as well. In addition, she will work on disseminating the results of the International Conference on Women in Physics to different groups in the Boston area, both giving talks and collecting feedback. She will also lead discussions in preparation for a follow-up meeting, tentatively scheduled for 2006. ***

AST-0302055 Sokoloski，Dr. Sokoloski被授予NSF天文学和天体物理学博士后奖学金，在哈佛-史密森天体物理中心开展研究和教育计划。 她将解决天体物理喷气机的创建，这是在宇宙中的许多不同大小的尺度上发现。这些高度集中的外流的原因被认为是围绕中心物体的吸积盘，但还没有得到很好的理解。 Sokoloski博士将对共生恒星周围的吸积盘进行详细研究，其中一颗白色矮星星星从红巨星的恒星风中吸积气体。该研究项目的三个方面将是：（1）共生星喷流的档案光谱调查，加上补充的无线电、光学和X射线成像观测;（2）探索共生星盘喷流的联系，包括可能产生潮汐畸变星星第一幅图像的干涉观测;（3）在选定的白矮星吸积器中，对产生喷流的盘内区域进行了详细的研究。我们的目标是使用共生星来区分竞争的喷流模型，无论是对于这些系统还是对于一般的天体物理喷流。Sokoloski博士还将致力于增加妇女和女孩对科学的参与。她将继续参与面向中学女生的“放眼未来”科学导师计划，并专注于招募同事参与。此外，她还将致力于向波士顿地区的不同群体传播国际物理学女性会议的成果，包括演讲和收集反馈。她还将主持讨论，筹备暂定于2006年举行的后续会议。***
