Touma from American University of Beirut, Lebanon Abstract Type : Oral Abstract Category : Stars,ISM and the Galaxy Abstract : The centres of many galaxies harbour Massive Black Holes which are surrounded by dense star clusters, known as Nuclear Star Clusters. Observations of nearby galaxies (our Galaxy and M31) show that these systems are very different in structure from other star clusters, say, globular clusters, in their deviations from spherical symmetry. These distortions could arise from dynamical, self-gravitating instabilities: e.g. it is known that stellar discs, having the counter-rotating populations of stars, are prone to a lopsided instability. I will present new investigations of other non-axisymmetric instabilities that may afflict an axisymmetric stellar disc corresponding to a particular kind of distribution function known as waterbag. |
