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-0502503Chakrabarti，Sukanya 博士。查克拉巴蒂获得了美国国家科学基金会天文学和天体物理学博士后奖学金，以在哈佛-史密森天体物理学中心开展研究和教育项目。 Chakrabarti 博士将通过应用辐射传输模型准确确定大质量恒星形成区域中的前恒星核心的质谱。她将利用自洽的二维辐射传输解决方案的结果来计算扁平结构中嵌入源的稳定性。确定这些结构的稳定性后，Chakrabarti 博士将对大块核心进行塌陷解，并计算所得密度结构的完整三维辐射传输解。为了解决当前对大块盘状结构的解释困境，Chakrabarti 博士将这些解决方案与对早期嵌入阶段的大块核心的观察进行比较。查克拉巴蒂还将实施一项计划，以促进和鼓励女性在物理科学领域的代表性。她的计划将由三个部分组成：创建物理科学女性协会（SWPS）分会，并为新团体发起和组织指导活动；创建一个科学交流论坛，供物理学和天文学领域的妇女和少数群体介绍其当前的研究；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、博士后学者和教师进行演讲和互动。
