Globular Star Clusters [PDF]

Nature, 1888
PHYSICAL aggregations of stars may be broadly divided into “globular” and “irregular” clusters. Although, as might have been expected, the line of demarcation between the two classes is by no means sharply drawn, each has its own marked peculiarities. We shall limit our attention, in the present article, to the first kind.

The Colors of Dwarf Elliptical Galaxy Globular Cluster Systems, Nuclei and Stellar Halos [PDF]

Astrophys.J. 613 (2004) 262-278, 2004
We present the results of a Hubble Space Telescope WFPC2 F555W and F814W survey of 69 dwarf elliptical galaxies (dEs) in the Virgo and Fornax Clusters and Leo Group. The $V-I$ colors of the dE globular clusters, nuclei, and underlying field star populations are used to trace the dE star-formation histories.

Dynamical Evolution of the Mass Function of Globular Star Clusters [PDF]

, 2001
We present a series of simple, largely analytical models to compute the effects of disruption on the mass function of star clusters. Our calculations include evaporation by two-body relaxation and gravitational shocks and mass loss by stellar evolution ...

On the Rate of Neutron Star Binary Mergers from Globular Clusters [PDF]

Astrophysical Journal, 2019
The first detection of gravitational waves from a neutron star–neutron star (NS–NS) merger, GW170817, and the increasing number of observations of short gamma-ray bursts have greatly motivated studies of the origins of NS–NS and neutron star–black hole ...

Massive Black Holes in Star Clusters. II. Realistic Cluster Models [PDF]

Astrophys.J. 613 (2004) 1143-1156, 2004
We have followed the evolution of multi-mass star clusters containing massive central black holes through collisional N-body simulations done on GRAPE6. Each cluster is composed of between 16,384 to 131,072 stars together with a black hole with an initial mass of M_BH=1000 Msun.

Multiple populations in globular clusters. Lessons learned from the Milky Way globular clusters [PDF]

, 2012
Recent progress in studies of globular clusters has shown that they are not simple stellar populations, being rather made of multiple generations. Evidence stems both from photometry and spectroscopy. A new paradigm is then arising for the formation of massive star clusters, which includes several episodes of star formation.

Dynamics of Globular Star Clusters [PDF]

Europhysics News, 1989
Globular star clusters are among the most beautiful objects in the sky (Fig. 1). But what attracts astronomers is that they are also among the oldest. The ages of their constituent stars give a tight estimate for the age of the Universe itself, and hence

The Origin of Gamma-Rays from Globular Clusters [PDF]

, 2010
Fermi has detected gamma-ray emission from eight globular clusters. We suggest that the gamma-ray emission from globular clusters may result from the inverse Compton scattering between relativistic electrons/positrons in the pulsar wind of MSPs in the globular clusters and background soft photons including cosmic microwave/relic photons, background ...

The Globular Cluster Migratory Origin of Nuclear Star Clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2014
Nuclear Star Clusters (NSCs) are often present in spiral galaxies as well as resolved Stellar Nuclei (SNi) in elliptical galaxies centres. Ever growing observational data indicate the existence of correlations between the properties of these very dense ...
