中文摘要
95-28563萨尔,史蒂文·萨尔博士计划通过三个平行的努力来解决恒星磁观测的分析和解释问题。首先是对200多颗GKM矮星的现有数据进行详细分析,确定磁场强度和填充因子(或上限)。二是对M矮星和活动亚巨星的场强和填充因子进行了新的红外观测。第三个是研究各种恒星大气中的通量管出现,并将解与本项目前两部分中发现的表面分布和磁场大小进行比较。***
英文摘要
95-28563 Saar, Steven Dr. Saar plans to address the analysis and interpretation of stellar magnetic observations through three parallel efforts. The first is a detailed analysis of existing data from over 200 GKM dwarf stars, determining the magnetic field strengths and filling factors (or upper limits). The second is to make new infrared observations of field strengths and filling factors for M dwarf and active subgiant stars. The third is to study flux tube emergence in a variety of stellar atmospheres and compare the solutions with the surface distribution and magnitude of magnetic fields found in the first two parts of this project. ***
