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…
Rings and spirals in barred galaxies. I Building blocks
E. Athanassoula, M. Romero-Gomez, J. J. Masdemont
In this paper we present building blocks which can explain the formation and properties both of spirals and of inner and outer rings in barred galaxies. We first briefly summarise…
Invariant manifolds as building blocks for the formation of spiral arms and rings in barred galaxies
M. Romero-Gomez, E. Athanassoula, J. J. Masdemont +1
We propose a theory to explain the formation of spiral arms and of all types of outer rings in barred galaxies, extending and applying the technique used in celestial mechanics to…
The formation of spiral arms and rings in barred galaxies
M. Romero-Gomez
We propose a theory to explain the formation of both spirals and rings in barred galaxies using a common dynamical framework. It is based on the orbital motion driven by the unstab…
