His findings, obtained by both direct numerical N-body modelling and using standard perturbation methods, offer a viable theoretical explanation for the observed configuration of young stars in the Galactic Centre. This marks a significant contribution to a topic of great interest in contemporary astrophysics..The author also shows in his thesis that a secular instability (m = 1 mode) may occur in the embedding spherical cluster of old stars. This increases the richness of possible evolution scenarios of the embedding cluster and may lead to effective feeding of supermassive black holes through tidal disruption of stars on extremely eccentric orbits.. | | 出版日期 | Book 2014 | | 关键词 | Dynamics of Star Clusters; Feeding of supermassive black holes; Galactic Center; Galactic Centre; Galact | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-03650-2 | | isbn_softcover | 978-3-319-37857-2 | | isbn_ebook | 978-3-319-03650-2Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer International Publishing Switzerland 2014 |
