CAREER: The formation of stars in groups

AST 0134739佛罗里达大学乔纳森·威廉姆斯博士。威廉姆斯被授予资金，在盖恩斯维尔的佛罗里达大学发起一项星星形成的研究计划。他将利用最新的望远镜仪器，通过在毫米和亚毫米波长下观察星团来研究星团中恒星的形成。虽然我们知道大多数恒星都是以星团的形式形成的，但是相对于单个恒星的形成来说，对星星成团形成的物理学了解甚少。 威廉姆斯博士将利用连续波长的观测来定位尘埃新生云中的原恒星，然后利用分子线的观测来研究周围气体的动力学和化学性质。原恒星的浓度和运动将被用来估计星团的相对年龄，使威廉姆斯博士能够追踪恒星和周围气体的化学和运动随时间的演变。 威廉姆斯博士将让研究生和本科生参与他的研究，并担任佛罗里达大学和西班牙加那利群岛天文学研究所之间新的国际学生交流的联络人。他还将参加他的大学的学生科学培训计划，指导一名高中生，每年夏天在一个为期七周的计划。

AST 0134739University of FloridaJonathan WilliamsDr. Williams is awarded funds to initiate a research program in star formation at the University of Florida in Gainesville. He will investigate the formation of stars in clusters by observing them at millimeter and submillimeter wavelengths, taking advantage of newly available telescope instrumentation. Although it is known that most stars form in clusters, the physics of star formation in groups is poorly understood relative to that of the formation of single stars. Dr. Williams will use observations at continuum wavelengths to locate protostars inside their dusty nascent clouds, and then use observations of molecular lines to investigate the dynamics and chemistry of the surrounding gas. The concentration and motions of the protostars will be used to estimate the relative age of a cluster, allowing Dr. Williams to trace the evolution of the chemistry and motion of the stars and surrounding gas as a function of time. Dr. Williams will involve graduate and undergraduate students in his research, and serve as liaison for a new international student exchange between the University of Florida and the Instituto de Astrofisica de Canarias in Spain. He will also participate in his university's Student Science Training Program by mentoring a high school student each summer in a seven week program.
