| 内容記述 | In order to monitor the various phenomena of comets, we continuously made the near-nucleus imaging observations of comets at National Astronomical Observatory, Mitaka. Here we report on the results of the observations of two spectacular comets. One is the analysis of photometry of C-2 emission images in the coma of comet Hyakutake (C/1996 B2). By comparing the production rates of C-2 radicals with C2H2 molecules, we conclude that the most C-2 radicals were originated from C2H2, while some of them might be produced from other parents. The second item is the analysis of the morphology of C-2 emission images in the coma of comet Hale-Bopp(C/1995 O1). By applying a ringmasking technique, we detected asymmetrical distribution of the C-2 molecules. The results of these two comets might suggest that a portion of C-2 radicals were formed by the disintegration of the small organic dust grains, like the so-called CHON particles. | |||||||||||||||
