Globular Clusters and Field Stars in the Bulge
Astrophysics and Space Science, 1999In this paper we discuss the characteristics of the stellar content of the galactic bulge excluding the stars within a few parsec from the galactic center. The bulge clusters and the field stars are comparedto the disk population. A scenario with a flattened bulge extending toabout 3–4 Kpc from the galactic center is presented.

The metal homogeneity of the globular star cluster M5
Monthly Notices of the Royal Astronomical Society, 1999This work is concerned with the precision measurement of the magnitudes of the stars across a large field of the galactic globular cluster M5. The colours of the red giants are subjected to a thorough statistical analysis in order to quantify the extent of any star-to-star variations in metal abundance within the cluster.

Unusual Variable Stars in the Globular Cluster M4
Astrophysics and Space Science, 1986With the development of observational techniques, at an accuracy of 0 . m 001 or higher, most stars have appeared to be variable and some have already been proposed to compile a non-variable star catalogue. We would not regard microvariability as unusual.

AGB Stars in Globular Clusters
2007From our study of AGB stars in globular clusters we present here three results: (1) Period-luminosity relations derived for the long-period variables in four clusters show a similar splitting into two sequences but also differ in the maximum luminosity reached.
