Dusty Evolved Star Kit（DESK）：用于拟合演化恒星光谱能量分布的Python包
The Dusty Evolved Star Kit (DESK): A Python package for fitting the Spectral Energy Distribution of Evolved Stars
摘要：
我们可以了解尘埃恒星周围的环境以及它们为宇宙贡献了多少物质的少数方法之一是通过不同波长的模型拟合它们的亮度，这些模型解释了能量如何通过尘埃传递。DESK是一个Python包，旨在比较不同恒星样本和模型网格的最佳拟合，以便更好地理解结果及其不确定性。该软件包适合光谱能量分布（SED）的演变恒星，使用测光或光谱，网格的辐射转移模型使用最小二乘法。该软件包包括新创建的网格使用各种不同的灰尘物种，和国家的最先进的灰尘增长网格。考虑到詹姆斯·韦伯太空望远镜（JWST）提供的大量红外数据，一种用于测试不同模型网格的可靠方法将尤为重要。
英文摘要：
One of the few ways that we can understand the environment around dusty stars and how much material they contribute back to the Universe, is by fitting their brightness at different wavelengths with models that account for how the energy transfers through the dust. The DESK is a python package designed to compare the best fits of different stellar samples and model grids for a better understanding of the results and their uncertainties. The package fits the Spectral Energy Distribution (SED) of evolved stars, using photometry or spectra, to grids of radiative transfer models using a least-squares method. The package includes newly created grids using a variety of different dust species, and state-of-the-art dust growth grids. A robust method for testing different model grids will be particularly important given the wealth of infrared data to come from the James Webb Space Telescope (JWST).
