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.
