Spectroscopic Studies of Stellar Activity

对表现出类似太阳色球表面活动的恒星的研究将继续使用宾夕法尼亚州立大学开发的仪器。将要研究的恒星类型包括天王星、星云恒星、弱线T-Tau星和经典T-Tau星。在过去的几年里，已经建立了大约2000个光谱的档案，并将在这项研究中利用，同时还将获得新的数据。还计划使用新的仪器进行红外观测，目标是测量恒星中的磁场。

Research on stars which show surface activity analogous to the solar chromosphere will be continued using instrumentation developed at Pennsylvania State University. Types of stars to be studied include BY Dra stars, RS CVn stars, weak-lined T Tau stars and classical T Tau stars. An archive of about two thousand spectra has been built up over a period of years and will be exploited in this research along with new data to be acquired. New instrumentation is also planned for infrared observations with the goal of measuring magnetic fields in stars.
