Interacting binary galaxies. III - Observations of NGC 1587/1588 and NGC 7236/7237
The catalog of isolated galaxy pairs prepared by Karachentsev has beenculled for its E-E constituents, and the results are reported. Radialvariations of rotation velocity and velocity dispersion are extractedfrom the spectroscopic data for each of the two galaxies of a givenpair. Such observations are described for two Karachentsev pairs, Nos.99 and 564. The observed disturbances in rotation velocity andluminosity distribution are discussed in terms of the gravitationalinteraction hypothesis. It is argued that observational evidence oftidal friction in action is evidenced by these findings. One of thehighest rotation rates known for an E2 galaxy of average luminosity isfound in NGC 1587, the brighter component of K99. Because this rotationis in the same sense as the binary orbital motion, the net angularmomentum in this isolated binary system is large, challenging simpletidal torque theories to identify the source of the momentum.
