Stein, Robert AST 96-16886 Drs. Stein and Hawley will model and develop diagnostics for analyzing dynamic phenomena in the solar atmosphere. Their theoretical calculations will follow the detailed interaction of the radiation and plasma motions in response to driving motions and rapid energy injection both in the presence and in the absence of magnetic fields. The analysis of line profiles, when compared to observation, will constrain the dynamics of the photosphere, chromosphere, and the transition region and shed light on the types of motions found. They will also model the behavior of these regions of the atmosphere in response to energy injection during flares and compare models with observations. ***

Stein，Robert AST 96-16886 Stein和Hawley博士将建立模型并开发诊断方法，用于分析太阳大气中的动态现象。 他们的理论计算将遵循辐射和等离子体运动的详细相互作用，以响应在存在和不存在磁场的情况下的驱动运动和快速能量注入。 与观测结果相比，对谱线剖面的分析将限制光球、色球和过渡区的动力学，并揭示所发现的运动类型，还将模拟这些大气区域对耀斑期间能量注入的响应行为，并将模型与观测结果进行比较。 ***
