A New Method of Observing and Investigating the Comet Dust from the Ground
-
摘要: 本文根据尘埃吸收系数Qv的不同模型(由实验和观测建立的模型)求解了不同性质的尘埃的辐射平衡方程.得到了性质不同,颗粒大小不同,日心距不同的尘埃的温度.如果我们把邻近两个波长的观测到的强度比值所确定的色温度当作尘埃的真实温度,那么我们就能够通过近红外的地面观测来研究尘埃的性质(而不要远红外的空间观测).Abstract: According to different models of the absorption coefficient of the comet dust, the equations of radiation balance are solved respectively. The temperatures of the dust with different properties, dimensions of grain and heliocentric distances have been obtained. If we take the colour temperature determined by the real temperature of the dust, then we can study the properties of the dust only by means of the near-infrared ground-based observations without need for far-infrared spatial observations.
