Globular Clusters in Dwarf and Giant Galaxies
Sidney van den Bergh
The luminosity distribution of globular clusters shows a dramatic dependence on parent galaxy luminosity. Dwarf galaxies contain far more faint globulars than do luminous galaxies.…
037-B327 in M31: Luminous Globular Cluster or Core of a Former Dwarf Spheroidal Companion to M31?
Jun Ma, Sidney van den Bergh, Hong Wu +6
037-B327 is of interest because it is both the most luminous and the most highly reddened cluster known in M31. Deep observations with the Advanced Camera for Surveys on the Hubble…
Chemical Compositions of Red Giant Stars in Old Large Magellanic Cloud Globular Clusters
Jennifer A. Johnson, Inese I. Ivans, Peter B. Stetson
We have observed ten red giant stars in four old Large Magellanic Cloud globular clusters with the high-resolution spectrograph MIKE on the Magellan Landon Clay 6.5-m telescope. Th…
Diameters of Open Star Clusters
Sidney van den Bergh
The present paper presents a tabulation of data on all 600 Galactic open clusters for which it is presently possible to calculate linear diameters. As expected, the youngest `clust…
Reddening distribution across the center of the globular cluster Omega Centauri
A. Calamida, P. B. Stetson, G. Bono +17
We present new medium-band uvby Stromgren and broad-band VI photometry for the central regions of the globular cluster Omega Cen. From this photometry we have obtained differential…
Globular Clusters in Dwarf Galaxies
Sidney van den Bergh
Data are presently available on the luminosities and half-light radii of 101 globular clusters associated with low-luminosity parent galaxies. The luminosity distribution of globul…
