论文摘要
染色体中的辐射损失在能量平衡中非常重要。在安静的太阳下，已经努力制作简单的查找表，以供色环辐射损失。在太阳耀斑期间，大气条件截然不同，而Gan＆Fang（1990）的当前可用食谱是由半经验模型构建的。这些食谱在耀斑条件下如何工作仍有待评估。我们旨在构建太阳耀斑的色球辐射损失的近似配方。我们遵循Carlsson＆Leenaarts（2012）的方法，以将光学较薄的辐射损失，逃生概率和电离分数制成，同时使用来自辐射流体动力模拟的耀斑模型的网格作为我们的数据集。我们提供新的查找表来计算耀斑的色球辐射损失。与以前的食谱相比，我们的食谱可以更好地近似耀斑的详细辐射损失。
Radiative losses in the chromosphere are very important in the energy balance. There have been efforts to make simple lookup tables for chromospheric radiative losses in the quiet Sun. During solar flares, the atmospheric conditions are quite different, and the currently available recipe of Gan & Fang (1990) is constructed from semi-empirical models. It remains to be evaluated how these recipes work in flare conditions. We aim to construct an approximate recipe of chromospheric radiative losses for solar flares. We follow the method of Carlsson & Leenaarts (2012) to tabulate the optically thin radiative loss, escape probability, and ionization fraction, while using a grid of flare models from radiative hydrodynamic simulations as our dataset. We provide new lookup tables to calculate chromospheric radiative losses for flares. Compared with previous recipes, our recipe provides a better approximation to the detailed radiative losses for flares.
