中文摘要
使用宾夕法尼亚州立大学开发的仪器,将继续研究显示出与太阳色球层类似的表面活动的恒星。要研究的恒星类型包括BY Dra星、RS CVn星、弱衬T Tau星和经典T Tau星。多年来建立了大约2000个光谱的档案,并将与新获得的数据一起用于本研究。新的仪器也计划用于红外观测,目的是测量恒星的磁场。
英文摘要
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.
