Scientific paper

The results of a search for galaxies with straight structural elements, usually spiral-arm rows ("rows" in the terminology of Vorontsov-Vel'yaminov), are reported. The list of galaxies that possess (or probably possess) such rows includes about 200 objects, of which about 70% are brighter than 14m. On the whole, galaxies with rows make up 6-8% of all spiral galaxies with well-developed spiral patterns. Most galaxies with rows are gas-rich Sbc-Scd spirals. The fraction of interacting galaxies among them is appreciably higher than among galaxies without rows. Earlier conclusions that, as a rule, the lengths of rows are similar to their galactocentric distances and that the angles between adjacent rows are concentrated near 120{deg} are confirmed. It is concluded that the rows must be transient hydrodynamic structures that develop in normal galaxies.
