RIMI: The Broader Context of Magnetic Activity In Cool Stars

9550561伊顿拟议的研究将通过研究不像以前用来确定恒星自转与磁活动关系的恒星群体，来定义金属丰度、极端恒星演化和非典型内旋转对磁活动的影响。被考虑的恒星群是(1)古老的贫金属恒星(人口2)，(2)快速旋转的单颗巨星，(3)凉爽、多风的巨星和超级巨星，以及(4)大量几乎不变的恒星。这项研究的直接影响将是更好地理解磁活动如何随着冷星的对流性质和自转而变化。四名本科生将参与这项拟议的工作。***

9550561 Eaton The proposed research would define the effects of metallicity, extreme stellar evolution and atypical internal rotation on magnetic activity by studying populations of stars less common than those used previously to define the relationship of stellar rotation to magnetic activity. Populations being considered are (1) old metal-poor (population 2) stars (2) rapidly rotating single giant stars, (3) cool, windy giants and super giants, and (4) large numbers of nearly constant stars. The immediate impact of this research will be a better understanding of how magnetic activity varies with convective properties and rotation of cool stars. Four undergraduate students will participate in the proposed work. ***
