摘要：

We use time-resolved charge-coupled device (CCD) images to assess the frequency of splitting of comets. When blinked on a computer, the CCD images provide relatively high and uniform sensitivity to comoving companions. We find that 3 comets are split in a sample of 49, and estimate that the cometary splitting rate is S approximately 0.01 per year per comet or larger. This large rate suggests that splitting may be an important destructive process for the cometary nuclei. (C) 1994 Academic Press, Inc.
