1979AISAO..11....3K Isolated triplets of galaxies. I - List Karachentseva, V. E.; Karachentsev, I. D.; Shcherbanovskii, A. L. Abstract. A list of 84 northern isolated galaxy triplets with component apparent magnitudes no fainter than 15.7 is compiled on the basis of a complete examination of Palomar Sky Survey prints. Equatorial coordinates, photographic apparent magnitudes, angular diameters, angular separations, morphological types, radial velocities, and other characteristics of the triplet members are provided, along with finding charts. Three main types of triplet configuration are distinguished: double, line, and triangle. It is shown that triple systems constitute 0.8% of northern galaxies brighter than 15.7 mag, that 64% of the triplets are 'completely isolated', and that 24% of the triplet members are elliptical and lenticular galaxies, while 76% are spirals and irregulars.
