Globular Clusters with Dark Matter Halos. II. Evolution in Tidal Field
Sergey Mashchenko, Alison Sills
In this second paper in our series, we continue to test primordial scenarios of globular cluster formation which predict that globular clusters formed in the early universe in the…
Globular Clusters with Dark Matter Halos. I. Initial Relaxation
Sergey Mashchenko, Alison Sills
In a series of two papers, we test the primordial scenario of globular cluster formation using results of high-resolutions N-body simulations. In this first paper we study the init…
The small Blue Straggler star population in the dense Galactic Globular Cluster NGC 6752
E. Sabbi, F. R. Ferraro, A. Sills +1
We have used high resolution WFPC2-HST and wide field ground-based observations to construct a catalog of blue straggler stars (BSS) which spans the entire radial extent of the glo…
The Universality of Initial Conditions for Globular Cluster Formation
Sergey Mashchenko, Alison Sills
We investigate a simple model for globular cluster (GC) formation. We simulate the violent relaxation of initially homogeneous isothermal stellar spheres and show that it leads to…
The contribution of primordial binaries to the blue straggler population in 47 Tucanae
M. Mapelli, S. Sigurdsson, M. Colpi +5
The recent observation (Ferraro et al. 2003b) of the blue straggler population in 47 Tucanae gives the first detailed characterization of their spatial distribution in the cluster…
