Evolution of the Mass Function of the Galactic Globular Cluster System
general stellar dynamics
2014/12/23
In this work we investigate the evolution of the mass function of the Galactic globular cluster system (GCMF) taking into account the effects of stellar evolution, two-body relaxation, disk shocking a...
We study the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution, exploring the physical consequences of external effects and examining evolutionary trends i...
Globular Cluster Evolution in M87 and Fundamental Plane Ellipticals
M87 Fundamental Plane Ellipticals
2014/12/23
The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamental plane elliptical...
Velocity Structure and Variability of [O III] Emission in Black Hole Host Globular Cluster RZ2109
Velocity Structure Variability Emission Globular Cluster
2011/10/12
We present a multi-facility study of the optical spectrum of the extragalactic globular cluster RZ2109, which hosts a bright black hole X-ray source. The optical spectrum of RZ2109 shows strong and ve...
The Peculiar Chemical Inventory of NGC 2419 -- An Extreme Outer Halo "Globular Cluster"
Peculiar Chemical Inventory Extreme Outer
2011/10/8
NGC 2419 is a massive outer halo Galactic globular cluster whose stars have previously been shown to have somewhat peculiar abundance patterns. We have observed seven luminous giants that are members ...
