Structure, Rotation, and Magnetic Fields in Starless Bok Globules. In order to better understand the conditions of star formation and processes in molecular clouds, Dr. Clemens will carry out an investigation of the relation between the structures and kinematics of small clouds and the properties of the magnetic fields threading those clouds. This study is aimed at understanding the physical conditions present in clouds prior to star formation, in particular the occurrence frequencies, distributions, and natures of embedded magnetic fields and angular momenta. Correlations will be sought between the magnetic and kinematic properties, such as aligned magnetic and rotation axes, vorticity or streaming of the field lines, and length scales in the magnetic field and gas clumps.

无星博克球体的结构、旋转和磁场。为了更好地了解分子云中恒星形成和过程的条件，克莱门斯博士将对小云的结构和运动学与贯穿这些云的磁场特性之间的关系进行研究。这项研究旨在了解恒星形成前云中存在的物理条件，特别是嵌入磁场和角动量的出现频率、分布和性质。将寻求磁学和运动学性质之间的关联，例如对齐的磁轴和旋转轴、场线的涡度或流动、磁场和气团中的长度尺度。
