Nearby Spiral Galaxy Globular Cluster Systems II : Globular Cluster
We present new metallicity estimates for globular cluster candidates in the Sd spiral NGC 300, one of the nearest spiral galaxies outside the Local Group. We have obtained optical spectroscopy for 44 Sculptor Group globular cluster candidates with the Boller and Chivens (B&C) spectrograph on the Baade Telescope at Las Campanas Observatory. There are 2 globular clusters in NGC 253 and 14 objects...
متن کاملKinematics of Globular Cluster Systems
I review the field of globular cluster system (GCS) kinematics, including a brief primer on observational methods. The kinematical structures of spiral galaxy GCSs so far appear to be broadly similar. The inferred rotation and mass profiles of elliptical galaxy halos exhibit a diversity of behaviors, requiring more systematic observational and theoretical studies.
متن کاملMonte Carlo Simulations of Globular Cluster Dynamics
We have developed a new parallel supercomputer code based on Hénon’s Monte Carlo method for simulating the dynamical evolution of globular clusters. This new code allows us to calculate the evolution of a cluster containing a realistic number of stars (N ∼ 10 − 10) in about a day of computing time. The discrete, star-by-star representation of the cluster in the simulation allows us to treat nat...
متن کاملBinary Stars and Globular Cluster Dynamics
In this brief proceedings article I summarize the review talk I gave at the IAU 246 meeting in Capri, Italy, glossing over the well-known results from the literature, but paying particular attention to new, previously unpublished material. This new material includes a careful comparison of the apparently contradictory results of two independent methods used to simulate the evolution of binary p...
متن کاملThe Formation of Globular Cluster Systems
I briefly review models for the formation of globular cluster (GC) systems, and summarize the observational properties (i.e., formation efficiencies, metallicity distributions, kinematics and ages) of the GC systems of M87 and M49: two thoroughly-studied elliptical galaxies. Many of the properties of the metal-poor GCs in these and other galaxies appear to be consistent with their formation in ...
