AST-0502503Chakrabarti, SukanyaDr. Chakrabarti 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. Dr. Chakrabarti will accurately determine the mass spectrum of prestellar cores in massive star-forming regions by application of a radiative transfer model. She will calculate the stability of embedded sources in flattened structures by using the results of self-consistent, two-dimensional radiative transfer solutions. Having determined the stability of these structures, Dr. Chakrabarti will perform collapse solutions of massive cores and calculate the full three-dimensional radiative transfer solutions of the resultant density structures. To resolve the current interpretational dilemma of massive disk-like structures, Dr. Chakrabarti will compare these solutions to observations of massive cores in their early embedded stages.Dr. Chakrabarti will also carry out a program to promote and encourage the representation of women in the physical sciences. Her program will consist of three components: creating a Society for Women in the Physical Sciences (SWPS) chapter and launching and organizing mentoring activities for the new group; creating a scientific exchange forum geared towards presentations by women and minorities in physics and astronomy on their current research; and sponsoring a colloquium series to bring female and minority scientists from major U.S. research institutions to speak and interact with students, postdoctoral scholars and faculty.

地址：苏坎尼亚，查克拉巴蒂查克拉巴蒂被授予NSF天文学和天体物理学博士后奖学金，以在哈佛-史密森天体物理中心开展一项研究和教育计划。查克拉巴蒂博士将通过应用辐射传输模型准确地确定大质量恒星形成区的恒星前核心的质谱图。她将使用自洽的二维辐射传输解的结果来计算扁平结构中嵌入源的稳定性。在确定了这些结构的稳定性后，查克拉巴蒂博士将执行大质量核心的坍塌解，并计算得到的密度结构的完整三维辐射传递解。为了解决目前大质量盘状结构的解释困境，查克拉巴蒂博士将把这些解决方案与对大质量岩芯早期埋藏阶段的观测进行比较。查克拉巴蒂还将实施一项计划，以促进和鼓励妇女在自然科学领域的代表性。她的计划将由三部分组成：创建女性物理科学学会(SWPS)分会，并为新组织发起和组织指导活动；创建一个科学交流论坛，面向物理学和天文学领域的女性和少数族裔介绍他们目前的研究；以及赞助一系列研讨会，让来自美国主要研究机构的女性和少数族裔科学家与学生、博士后学者和教职员工进行演讲和互动。
