Iron and neutron-capture element abundance variations in the globular cluster M2 (NGC 7089) [PDF]
, 2014 We present CN and CH indices and CaII triplet metallicities for 34 giant stars and chemical abundances for 33 elements in 14 giants in the globular cluster M2.

Globular Cluster Distance Determinations [PDF]
, 1998 The present status of the distance scale to Galactic globular clusters is reviewed. Six distance determination techniques which are deemed to be most reliable are discussed in depth. These different techniques are used to calibrate the absolute magnitude

New Astronomy, 2000 The dynamics of a close binary system of globular clusters is considered. It is shown that the star transfer process from one of the components to the other should lead to the decrease of dimension of the first cluster with simultaneous increase of the dimension of the second cluster.

Globular Clusters in the LMC [PDF]
Symposium - International Astronomical Union, 1980 Because globular clusters are the oldest stellar systems, they should be sensitive probes of the early dynamical and chemical evolution of galaxies. Since some success has been achieved in understanding these problems in our own galaxy, it seems appropriate to see what can be learned from the clusters in the Large Magellanic Cloud (LMC).

Dynamical Substructures of Galactic Globular Clusters II. NGC 6934 [PDF]
Journal of Astronomy and Space Sciences, 2004 The variations of the dynamical substructures of NGC 6934 have been investigated by means of performing point spread function stellar photometry and the surface photometry on BV CCD images of NGC 6934.

A NEW DISTANT MILKY WAY GLOBULAR CLUSTER IN THE PAN-STARRS1 3π SURVEY [PDF]
, 2014 We present a new satellite in the outer halo of the Galaxy, the first Milky Way satellite found in the stacked photometric catalog of the Panoramic Survey Telescope and Rapid Response System 1 (Pan-STARRS1) Survey. From follow-up photometry obtained with

HST Imaging of Globular Clusters in the Edge--on Spiral Galaxies NGC 4565 and NGC 5907
, 1999 We present a study of the globular cluster systems of two edge-on spiral galaxies, NGC4565 and NGC5907, from WFPC2 images in the F450W and F814W filters.

CCD Photometry of the Globular Cluster M30 [PDF]
Journal of Astronomy and Space Sciences, 1996 We present UBV CCD photometry of the metal-poor globular cluster M30. The data were obtained using the 40 inch telescope at Mt. Stromlo and Siding Spring Observatory (MSSSO).

Dynamical Substructures of Galactic Globular Clusters III. NGC 7006 [PDF]
Journal of Astronomy and Space Sciences, 2005 To study the effects of giant population on dynamical substructures of the central region of NGC 7006, we examine the radial variations of ellipticity and position angle on BV stellar photometry using ellipse fitting technique.

The outer halo globular cluster system of M31 – II. Kinematics [PDF]
, 2014 We present a detailed kinematic analysis of the outer halo globular cluster system of the Andromeda galaxy (M31). Our basis for this is a set of new spectroscopic observations for 78 clusters lying at projected distances between Rproj 20-140 kpc from ...
