ABSTRACTStein, Robert"Convection, Oscillations and GONNNNG"AST-9819799This project is an investigation of the interaction of solar convection, magnetic fields and surface oscillations. The specific goals of the project include achieving a better physical understanding of: (1) the coupling between surface and bottom boundary layers of the solar convection zone; (2) p-mode oscillation frequencies; (3) the oscillation modes; and (4) the uniqueness of models fit to data, as well as the 'inverse' problem of using data to set constraints on the models. Data from GONG and SOHO will be compared to detailed computed simulations of magnetic and convection phenomena near the solar surface. An attempt will be made to reconcile these fits to surface phenomena with predictions made by idealized models for convective layers too deep to observe directly.

本项目是对太阳对流、磁场和表面振荡相互作用的研究。 该项目的具体目标包括从物理上更好地了解：（1）太阳对流区表面和底部边界层之间的耦合;（2）p模式振荡频率;（3）振荡模式;（4）模型与数据拟合的独特性，以及利用数据对模型设定约束条件的“逆”问题。 来自GONG和SOHO的数据将与太阳表面附近的磁和对流现象的详细计算模拟进行比较。 我们将试图使这些与地面现象的拟合与理想化模式对太深而不能直接观测的对流层所作的预测相一致。
