Early Stages of Massive Protostars and Dusty Galaxies: Integrating the Observational and Theoretical Arenas

AST-0502503 Chakrabarti，SukanyaDr. Chakrabarti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。Chakrabarti博士将通过辐射传输模型的应用，准确地确定大质量恒星形成区星前核心的质谱。她将通过使用自洽的二维辐射传递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之后，Chakrabarti博士将执行大质量核心的崩溃解决方案，并计算所得密度结构的完整三维辐射传输解决方案。为了解决目前大规模盘状结构的解释困境，Chakrabarti博士将这些解决方案与早期嵌入阶段的大规模核心的观察进行比较。Chakrabarti博士还将开展一项计划，以促进和鼓励女性在物理科学中的代表性。她的计划将包括三个组成部分：创建一个物理科学妇女协会（SWPS）分会，并为新的团体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妇女和少数民族介绍他们目前的研究;并赞助一系列座谈会，让来自美国主要研究机构的女性和少数民族科学家与学生、博士后学者和教师进行演讲和互动。

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.
