针对当前星模拟器完全丢失恒星光谱信息的缺陷,本文进行了星光颜色模拟方面的初步研究.首先,选择合适的星表并确定要进行颜色模拟的恒星星号,得到该星色指数等一系列信息;同时,根据有关资料,推导出恒星色指数与色温之间的函数关系;至此,确定该星色温.其次,由黑体辐射公式,计算出黑体在此温度下的辐射特性.然后,根据色度学原理,把黑体在此温度下的辐射量刺激值积分,得到该色温的总刺激值,归一化就可得到相应的色度坐标,完成了恒星的星光颜色模拟.最后,说明并解释了本研究方案的不足之处.模拟实验结果证明了星光颜色模拟的可行性.

A preliminary research on color simulation of stars was done to overcome the limitation of lack of spectrum information of stars in a star simulator nowadays. First of all, choose the suitable star catalog, decide the star number which would be researched on color simulation, and find the color index of the star. Simultaneously, deduce the functional relationship between the color index and the color temperature. And the color temperature of the star was decided. Then, calculate the radiation property of the blackbody under the color temperature. After that, according to the theory of colourometry, integrate the stimulus values of the blackbody and normalize the results to get the corresponding colourometry coordinates. Therefore, the color simulation of stars is implemented. Finally, explain the limitation of the research program. The experimental results show the feasibility of color simulation of stars.
