Most of our knowledge of the chromosphere of the sun is based on spectral features which originate in hot plasmas. However, the chromosphere is very inhomogeneous and also contains relatively cool regions. The infrared bands from CO will be observed to study this cooler gas in the sun and other stars. Numerical simulations will be constructed to understand these observations in conjunction with observations of the hot plasma. This work will shed light on the elusive question of the source of heating of the solar chromosphere.

我们对太阳色球层的大部分知识是基于热等离子体的光谱特征。然而，色球层非常不均匀，也包含相对较冷的区域。来自CO的红外波段将被用来研究太阳和其他恒星中的这种较冷的气体。数值模拟将与热等离子体的观测相结合来理解这些观测结果。这项工作将阐明太阳色球层的加热来源这一难以捉摸的问题。
