Dissipationless collapse of a set of N massive particles | F. Roy

30 Oct 2003 | Journal: | Mon.Not.Roy.Astron.Soc. 348 (2004) 62-72 | Subject: | astro-ph | Abstract: | The formation of self-gravitating systems is studied by simulating the collapse of a set of N particles which are generated from several distribution functions. We first establish that the results of such simulations depend on N for small values of N. We complete a previous work by Aguilar and Merritt concerning the morphological segregation between spherical and elliptical equilibria. We find and interpret two new segregations: one concerns the equilibrium core size and the other the equilibrium temperature. All these features are used to explain some of the global properties of self-gravitating objects: origin of globular clusters and central black hole or shape of elliptical galaxies. | Source: | arXiv, astro-ph/0310871 | Services: | Forum | Review | PDF | Favorites |
