The PI's objective in this project is providing detailed spectral signatures of coronal loops from model calculations which consistently account for dynamics and energetics from the corona through the chromosphere. He will simulate a variety of loop lengths and heating mechanisms, and will examine thermal stability. The PI will also perform model calculations of coronal loops extending into the chromosphere using self-consistent radiation hydrodynamic calculations to provide definitive spectral signatures of these loops. He will use the ALTAIR, a highly sophisticated computational tool that integrates hydrodynamics and frequency dependent radiative transfer code and increases the speed in solving generalized non-LTE problems.***

PI在该项目中的目标是通过模型计算提供日冕环的详细光谱特征，这些模型计算一致地解释了从日冕到色球层的动力学和能量学。 他将模拟各种回路长度和加热机制，并将检查热稳定性。 PI还将使用自洽辐射流体动力学计算对延伸到色球层的日冕环进行模型计算，以提供这些环的明确光谱特征。 他将使用ALTAIR，这是一种高度复杂的计算工具，集成了流体力学和频率相关辐射传输代码，并提高了解决广义非LTE问题的速度。
