Abstract: The data in Westerlund's (1971) catalog of carbon stars have been analyzed in order to determine whether a significant excess of carbon-star pairs exists, as has been previously claimed. We present a simple and consistent statistical method for comparison of observed and random separation distributions. The differential separation distribution shows no strong evidence for an excess number of pairs, except possibly at very small ( 0?03) separations. The frequency distribution of magnitude differences for different separations and the large implied physical separations suggest to us that most of these pairs are not physical. Key words: carbon stars-binary stars
