Studies of the Large Scale Structure of the Sun's Corona andMeter-Decameter Bursts

利用克拉克湖多频射电日像仪获得的高空间和时间分辨率图像，我们将研究日冕中的米-十米射电源。无线电天气图和安静的太阳图将用于研究和模拟大型结构，如流带和日冕洞。脉冲爆发观测将与软x射线数据结合使用，研究日冕物质抛射的几个方面，包括结构和等离子体参数，高度时间演化，CME，耀斑和冲击的关系，以及慢冲击时粒子的加速。总的目标是利用现有的数据来阐明最终影响地球的太阳脉冲抛射的性质。

Using high spatial- and temporal-resolution images acquired with the Clark Lake multifrequency radioheliograph, we will study meter-decameter radio sources in the solar corona. Radio synoptic charts and quiet Sun maps will be used to study and model large-scale structures such as streamers and coronal holes. Impulsive burst observations will be used in conjunction with soft X-ray data to study several aspects of coronal mass ejections, including structure and plasma parameters, height-time evolution, the relationship of CME's, flare and shocks, and acceleration of particles at slow shocks. The overall aim is to use already existing data to elucidate the nature of impulsive ejections from the sun which ultimately impact the earth.
