Physics Letters A, 2000
Abstract Here we put forward some arguments in favour of the existence of slow bars. More then a half of spiral galaxies have in their central regions a bar — a structure in the form of triaxial ellipsoid. Historically two models of the bar were developed — those of the so called “slow” and “fast” bars. In both cases the bar is in some resonance with

The Secrets of Barred Spiral Galaxies
Global Research Journal, 2022Black holes start their lives as big dead stars in the depth of the universe. As they move towards the outer universe they gather cosmic dust, asteroids, planets, eventually they get bigger. The gravitational force increases and continues this process for billions of years. When an asteroid enters the gravitational field of an ever-growing dead star, it

The barred spiral structure of galaxies
Chinese Astronomy and Astrophysics, 1984Abstract We have carried out a preliminary analysis of barred spirals using a gas-dynamical model. By means of the method of integral transform given in a previous paper [1], an analytical solution has been obtained which is in fair agreement with observations.

STRUCTURES OUT OF CHAOS IN BARRED-SPIRAL GALAXIES
International Journal of Bifurcation and Chaos, 2012We review the dynamical mechanisms we have found to support the morphological features in barred-spiral galaxies based on chaotic motions of stars in their gravitational fields. These morphological features are the spiral arms, that emerge out of the ends of the bar, but also shape the bar itself.
