Collaborative Project: Doppler Imaging of Spatially ResolvedFeatures on Rotating Stars

该奖项支持一项为期两年的计划，该计划将使用一种称为多普勒成像的技术来研究某些类型恒星的表面结构。研究人员将在较冷的双星上获得大型恒星黑子（类似于太阳上的太阳黑子）的图像。这些黑子追踪了出现的磁通量，这些黑子随时间的分布和演变提供了这些恒星中磁和对流过程的基本信息。该研究计划将继续改进多普勒成像技术，并提供对几个不同恒星和恒星系统的长期监测。

This award supports a two year program that will use a technique known as Doppler imaging to study the surface structure on certain types of stars. The investigators will derive images of large star spots (analagous to sunspots on our Sun) on cool binary stars. These spots trace the emergent magnetic flux and the distribution and evolution of these spots over time provides fundamental information on magnetic and convective processes in these stars. The research program will continue to improve the Doppler imaging technique and provide long term monitoring of several different stars and stellar systems.
