An Instability in Triaxial Stellar Systems
Fabio Antonini, Roberto Capuzzo-Dolcetta, David Merritt
The radial-orbit instability is a collective phenomenon that has heretofore only been observed in spherical systems. We find that this instability occurs also in triaxial systems,…
Self-consistent simulations of Nuclear Cluster formation through Globular Cluster orbital decay and merging
R. Capuzzo-Dolcetta, P. Miocchi
We present results of fully self-consistent N-body simulations of the motion of four globular clusters moving in the inner region of their parent galaxy. With regard to previous si…
Merging of globular clusters within inner galactic regions. II. The Nuclear Star Cluster formation
R. Capuzzo-Dolcetta, P. Miocchi
In this paper we present the results of two detailed N-body simulations of the interaction of a sample of four massive globular clusters in the inner region of a triaxial galaxy. A…
Self-consistent models of triaxial cuspy galaxies with dark matter halos
R. Capuzzo-Dolcetta, L. Leccese, D. Merritt +1
We have constructed realistic, self-consistent models of triaxial elliptical galaxies embedded in triaxial dark matter halos. Self-consistent solutions by means of the standard orb…
Tidal tails around globular clusters
M. Montuori, R. Capuzzo-Dolcetta, P. Di Matteo +1
We present the results of detailed N-body simulations of clusters moving in a realistic Milky Way (MW) potential. The strong interaction with the bulge and the disk of the Galaxy l…
On the Origin of Early-type Galaxies Nuclei
R. Capuzzo-Dolcetta, P. Miocchi
The ACS Virgo cluster survey by Cote' and collaborators shows the presence of compact nuclei at the photocenters of many early-type galaxies. It is argued that they are the low-mas…
