介绍了一种新的用于分析小行星和其他固体近红外光谱的热物理模拟软件包谢尔曼。该模型的功能，它用来解决表面和地下温度的方法，以及它输出的合成数据进行了描述。一组验证测试表明，谢尔曼产生准确的输出在各种特殊情况下，正确的结果可以从理论推导出来。这些情况包括热方程的一系列解，其中热惯性可以具有任何值，热物理性质可以随深度和温度而变化。附录描述了一种新的近似方法，用于估计球形截面陨石坑内的表面温度，比标准方法更适合于模拟短波长的红外光束。
SHERMAN, a new thermophysical modeling package designed for analyzing near-infrared spectra of asteroids and other solid bodies, is presented. The model’s features, the methods it uses to solve for surface and subsurface temperatures, and the synthetic data it outputs are described. A set of validation tests demonstrates that SHERMAN produces accurate output in a variety of special cases for which correct results can be derived from theory. These cases include a family of solutions to the heat equation for which thermal inertia can have any value and thermophysical properties can vary with depth and with temperature. An appendix describes a new approximation method for estimating surface temperatures within spherical-section craters, more suitable for modeling infrared beaming at short wavelengths than the standard method.
