Abstract: ATM 00-77624Proposal Title: Infrared Diagnostic DevelopmentPrincipal Investigator: Matthew Penn, California State University, Northridge The investigators will determine variations in magnetic structure with height above the visible surface of the Sun. The main effort is to use the San Fernando Observatory Vacuum Telescope (SFOVT) to make a variety of observations of the photosphere and chromosphere at infrared wavelengths. Observations at infrared wavelengths of spectral lines formed at different altitudes will allow the investigators to make Zeeman magnetic field measurements. The investigators will perform a fractal analysis of the spatial structure of the magnetic field, and study the vertical extent of magnetic structures observed at low altitudes, the so-called moss. With high time resolution they will follow dynamic changes in magnetic fields prior to filament eruptions, and low-level outflows observed in coronal holes, possibly implying a low altitude source for solar wind. The proposed research will initiate a new direction for the SFOVT, utilizing a recently acquired, high performance infrared camera.

摘要：ATM 00- 77624提案标题：红外诊断开发首席研究员：马修佩恩，加州州立大学，北岭研究人员将确定磁结构的变化与高度以上的太阳可见表面。主要的工作是利用圣费尔南多天文台真空望远镜（SFOVT）在红外波段对光球层和色球层进行各种观测。在不同高度形成的光谱线的红外波长下的观测将使研究人员能够进行塞曼磁场测量。研究人员将对磁场的空间结构进行分形分析，并研究在低海拔观察到的磁性结构的垂直范围，即所谓的苔藓。它们将以高时间分辨率跟踪暗条爆发前磁场的动态变化，以及在冕洞中观察到的低空外流，这可能意味着太阳风的低空来源。拟议的研究将为SFOVT开辟一个新的方向，利用最近获得的高性能红外相机。
