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.

AST-0502503 Chakrabarti，Sukanyadr。 Chakrabarti被授予NSF天文学和天体物理学博士后奖学金，以在哈佛大学的天体物理学中心进行研究和教育计划。 Chakrabarti博士将通过应用辐射转移模型准确地确定大量星形区域中Prestellar核心的质谱。她将通过使用自洽的二维辐射传递溶液的结果来计算扁平结构中嵌入式源的稳定性。确定了这些结构的稳定性后，Chakrabarti博士将执行大规模核心的塌陷溶液，并计算所得密度结构的完整三维辐射转移溶液。为了解决类似磁盘样结构的当前解释困境，Chakrabarti博士将将这些解决方案与早期嵌入式阶段的大规模核心观察进行比较。 Chakrabarti还将执行一项计划，以促进和鼓励妇女在体育科学中的代表。她的计划将包括三个组成部分：在体育科学（SWP）章节中为妇女创建社会，并为新小组推出和组织指导活动；建立一个科学交流论坛，旨在旨在由妇女和少数民族在物理学和天文学方面的演讲；并赞助了座谈会系列，以带来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交谈和互动。
