La inestabilidad de órbitas radiales en la formación de galaxias por colapso no disipativo
Aguilar and Merritt (1990, Ap. J., 354, 33) have showed that the radial orbit instability, by building up triaxial systems, plays a crucial role in the galaxy formation by dissipationless colapse. We show here that Hubble's expansion and the inhomogeneity of the material may be an alternative w...

| Sumario: | Aguilar and Merritt (1990, Ap. J., 354, 33) have showed that the radial orbit instability, by building up triaxial systems, plays a crucial role in the galaxy formation by dissipationless colapse. We show here that Hubble's expansion and the inhomogeneity of the material may be an alternative way of preventing bar formation, instead of velocity dispersion or rotation of the material. |
