内容記述 | An attempt to reduce the effects of black materials from the spectral reflectances of meteorites or asteroids was made by using the Kubelka-Munk function with minor modifications. Our reduction method has for its object to make clear the spectral contrast which is suppressed by the effects of the black materials. For this purpose, spectral reflectances (0.25-2.5μm) were measured on samples of the Yamato-75258 meteorite (LL6 chondrite) which contain various amounts of black materials (carbon black or magnetite), and their changes with the effects of black materials were examined. Only a few weight percents of the black materials lower the reflectivity and weaken the absorption band strength. On the basis of these reflectance measurements, we tried to construct the spectral reflectance curve by reducing the effects of the black material from that of the Murchison meteorite and to compare the constructed curve with the spectral reflectance of Ceres. The results imply that the material which contains less carbon than the Murchison meteorite, is a better candidate for the surface material of Ceres. Our method will be a useful one for making the spectral contrast clear, although some problems remain to be solved. | |||||
