标题： Radiative transfer in Doppler Imaging

摘要： 现代多普勒成像（DI）技术允许基于特定强度光谱的准确计算来重建恒星表面的不同结构。 新的应用如磁场矢量的映射对辐射转移（RT）求解器提出了非常严格的要求，它应该准确、快速，并且对数值误差具有鲁棒性。 我们描述了对我们的新磁场DI代码INVERS10的三种不同算法的评估。 我们还展示了使用新代码进行的数值实验的初步结果。 显示英文摘要

摘要： The modern Doppler Imaging (DI) technique allows the reconstruction of different stellar surface structures based on accurate calculation of spectra of specific intensity. New applications like the mapping of the magnetic field vector put very stringent requirements on the radiative transfer (RT) solver which should be accurate, fast, and robust against numerical errors. We describe the evaluation of three different algorithms for our new magnetic DI code INVERS10. We also show the first results of numerical experiments made with the new code.
