An RUI Comprehensive Investigation of Red Dwarf Stars: Ages,Rotation, Magnetic Dynamo Activity and Habitability of Hosted Planets

在他的项目中，Guinan博士和合作者将把早期对太阳型恒星的研究扩展到较冷的未进化恒星。 主要目标是测量恒星自转如何随时间减慢，并探索年龄，自转速率和磁驱动活动（如色球发射和日冕X射线通量）之间的关系。 该项目将研究已知年龄的星团中的低质量恒星;如果能够找到良好的年龄-活动-旋转关系，则可以确定非星团恒星的年龄。新的卫星实验正在确定大量的旋转周期，并发现低质量恒星周围的行星，确定这些系统的年龄将非常重要。X射线通量及其演化的确定将对位于恒星“可居住区”的行星上的生命是否会受到X射线的影响产生影响。 该项目将为本科生提供研究机会，并将支持公众在公共教育和宣传方面的努力。

In his project, Dr. Guinan and collaborators will extend an earlier study on solar-type stars to cooler unevolved stars. The main goals are to measure how stellar rotation slows with time and to explore the relation between ages, rotation rates, and magnetically-driven activity such as chromospheric emission and coronal X-ray flux. The project will study low-mass stars in clusters of known age; if a good age-activity-rotation relation can be found, then the ages of non-cluster stars can be determined. New satellite experiments are determining a large number of rotation periods and discovering planets around low-mass stars, and it would be important to determine ages for these systems. Determination of the X-ray flux and its evolution will have an impact on whether life would be affected by X-rays on planets in the "habitable zone" of their stars. The project will provide research opportunities for undergraduate students, and will support efforts public in public education and outreach.
