Scientific paper

Observational data are considered to suggest that disc galaxies have a spiral or barred-spiral structure. Using the gasdynamic model for galaxies and a previously proposed method of integral-transformation, the barred-spiral structure is investigated and an analytical solution is obtained. It gives the large-scale pattern of barred-spirals, which agrees fairly well with observational data.
