论文摘要
太阳风模型预测，在太阳风中从太阳中散发出的质量通量应对太阳风加速的电晕温度极为敏感。我们使用原位和遥感观测值的组合对冠状孔和活动区域中的这种预测进行了直接测试。对于冠状孔，温度从0.8 mk到1.2 mk的温度增加50％与冠状质量通量的三倍有关。在活跃区域内的2 MK温度以上的温度下，这种趋势得以维持，温度升高4倍，相对于冠状质量通量增加200倍。
Solar wind models predict that the mass flux carried away from the Sun in the solar wind should be extremely sensitive to the temperature in the corona, where the solar wind is accelerated. We perform a direct test of this prediction in coronal holes and active regions, using a combination of in-situ and remote sensing observations. For coronal holes, a 50% increase in temperature from 0.8 MK to 1.2 MK is associated with a tripling of the coronal mass flux. At temperatures over 2 MK, within active regions, this trend is maintained, with a four-fold increase in temperature corresponding to a 200-fold increase in coronal mass flux.
