5 Sep 2001 | | Journal: | Mon.Not.Roy.Astron.Soc. 334 (2002) 310 | | Subject: | astro-ph | | Affiliation: | 1,2), Christian Einsel , Hyung Mok Lee (1,3), Rainer Spurzem, Myung Gyoon Lee ( Seoul National University, Korea Astronomisches Rechen-Institut, Germany Institute of Space and Astronautical Science, Japan | | Abstract: | We present the first post core collapse models of initially rotating star clusters, using the numerical solution of an orbit-averaged 2D Fokker-Planck equation. Based on the code developed by Einsel & Spurzem (1999), we have improved the speed and the stability and included the steady three-body binary heating source. We have confirmed that rotating clusters, whether they are in a tidal field or not, evolve significantly faster than non-rotating ones. Consequences for observed shapes, density distribution, and kinematic properties of young and old star clusters are discussed. The results are compared with gaseous and 1D Fokker-Planck models in the non-rotating case. | | Source: | arXiv, astro-ph/0109062 | | Services: | Forum | Review | PDF | Favorites | |
