Chaos in core-halo gravitating systems | | T. Ghahramanyan

17 Jan 2007 | | Abstract: | Chaotic dynamics essentially defines the global properties of gravitating systems, including, probably, the basics of morphology of galaxies. We use the Ricci curvature criterion to study the degree of relative chaos (exponential instability) in core-halo gravitating configurations. We show the existence of a critical core radius when the system is least chaotic, while systems with both smaller and larger core radius will typically possess stronger chaotic properties. | | Source: | arXiv, astro-ph/0701491 | | Services: | Forum | Review | PDF | Favorites | |
