Evolution of Circumstellar Disks: A Study of Accretional Variability and Disk Lifetimes.

AST-0507310Bary，JeffreyDr.巴里被授予美国国家科学基金会天文学和天体物理学博士后奖学金，在弗吉尼亚大学开展一项研究和教育计划。了解围绕着年轻的类太阳恒星的原行星盘对于确定行星系统形成的频率是至关重要的。巴里博士将用多方面的观测方法解决盘耗散和星盘相互作用的问题，以研究拥有星盘的年轻恒星的演化。他的研究计划将致力于回答这样一个问题：无处不在的周星盘是否导致了行星系统的无处不在？巴里博士还将为职前和在职教师设计和领导专业发展研讨会/研讨会，并开展各种公共推广活动。

AST-0507310Bary, JeffreyDr. Bary is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the University of Virginia. Understanding the proto-planetary disks that encircle young Sun-like stars is essential to determining the frequency with which planetary systems form. Dr. Bary will address questions of disk dissipation and star-disk interactions with a multi-faceted observational approach to study the evolution of young stars that harbor circumstellar disks. His research program will work towards answering the question: Does the ubiquity of circumstellar disks lead to the ubiquity of planetary systems?Dr. Bary will also design and lead professional development seminars/workshops for pre-service and in-service teachers as well as perform a variety of public outreach activities.
