Rings, spirals and manifolds
E. Athanassoula, M. Romero-Gomez, J. J. Masdemont
Two-armed, grand design spirals and inner and outer rings in barred galaxies can be due to orbits guided by the manifolds emanating from the vicinity of the L1 and L2 Lagrangian po…
The formation of spiral arms and rings in barred galaxies
M. Romero-Gomez, E. Athanassoula, J. J. Masdemont +1
We propose a new theory to explain the formation of spiral arms and of all types of outer rings in barred galaxies. We have extended and applied the technique used in celestial mec…
The formation of spiral arms and rings in barred galaxies
M. Romero-Gomez, E. Athanassoula, J. J. Masdemont +1
In this and in a previous paper (Romero-Gomez et al. 2006) we propose a theory to explain the formation of both spirals and rings in barred galaxies using a common dynamical framew…
On the origin of rR_1 ring structures in barred galaxies
M. Romero-Gomez, J. J. Masdemont, E. Athanassoula +1
We propose a new theory for the formation of rR_1 ring structures, i.e. for ring structures with both an inner and an outer ring, the latter having the form of ``8''. We propose th…
