WebWierzbicki, T.; Bhat, S.U., 1986: Initiation and propagation of buckles in pipelines Webthat B/PS bulges could be due to the thickening of bars in the disks of spiral galaxies. They showed that soon after a bar develops through the usual bar instability, it buckles, thickens, and settles with a larger velocity dispersion and thickness. When highly inclined, the bar then appears peanut-shaped
