931485194 Balachandran This research planning grant will allow the PI to plan and begin a research program directed at better understanding the role of rotation in the evolution of stars. There is a body of evidence which strongly suggests that the rotational history of a star plays a significant role in determining its structure and surface composition. The goal of this project is to quantify the effects of rotation by observing young, embedded pre-main sequence stars, by measuring the abundance of lithium and rotational velocities for stars in clusters of various ages and by measuring the CNO abundances of stars in globular clusters. ***

小行星931485194 这项研究计划拨款将使PI计划并开始一项旨在更好地理解恒星演化中旋转作用的研究计划。 有大量的证据有力地表明，一颗星星的自转历史在决定其结构和表面成分方面起着重要的作用。 该项目的目标是通过观测年轻的嵌入式主序前恒星，测量不同年龄星团中恒星的锂丰度和旋转速度，以及测量球状星团中恒星的CNO丰度，来量化旋转的影响。 ***
