内容記述 | We measured the reflectance change of high-porosity dust agglomerate (so-called dust cake) at small phase angle. The wavelength ranged from 0.97 to 1.6 micrometer. The porosity of the dust cake was varied from about 84 to 70 percent. We searched for changes in the behavior of opposition surge with respect to porosity, which was predicted by a previous numerical simulation. However, the results of our measurements do not indicate any systematic dependence of the opposition surge on the porosity of the dust cake. This is probably why the porosity of the near surface zone does not change with imposed pressure (from about 10(exp 3) to 2 x 10(exp 4) Pa). On the other hand, the opposition surge is more enhanced at the wavelength where the reflectance is lower. This tendency is consistent with the opposition surge found for high albedo asteroids. | |||||
