Mutel, Robert L. 94-17353 Mutel will conduct a three-year program to use the VLA and VLBA to investigate properties of non-thermal radio emissions from close, late-type binaries which show evidence for enhanced activity. It is a 3-part program: 1) to determine the spatial distribution of radio emission in the outer magnetospheres of several binaries with the VLBA; 2) to determine the frequency dependence of the polarization, spectra and time history of several classes of active binaries using the VLA; and 3) to use the VLA and VLBA observations to test and develop quantitative models for the geometry and dynamics of stellar magnetospheres for close binaries. ***

Mutel, Robert L. 94-17353 Mutel 将开展一项为期三年的计划，利用 VLA 和 VLBA 来研究近距离晚型双星的非热射电发射特性，这些辐射显示出活动增强的证据。 该计划由 3 部分组成：1）利用 VLBA 确定几个双星外磁层中无线电发射的空间分布； 2) 使用 VLA 确定几类活动双星的偏振、光谱和时间历史的频率依赖性； 3）利用VLA和VLBA观测来测试和开发邻近双星恒星磁层几何和动力学的定量模型。 ***
