Invariant manifolds in barred galaxy simulations. III. Self-regulated weakening of strong spiral arms

T. Soler-Terricabras, S. Roca-Fà brega, M. Romero-Gómez

The paper investigates why strong spiral arms in barred galaxies weaken, showing that self‑gravitating spirals shift the galaxy’s Lagrangian points, disrupting invariant‑manifold d…
