Abstract:
We present for the first time a catalogue of SX Phe-type pulsating
variables in globular clusters. In addition, SX Phe variables
discovered in the Carina dwarf galaxy and other ones probably
belonging to the Sagittarius dwarf galaxy are included. This catalogue
is intended to be an up-dated list of all the SX Phe stars, in
globular clusters and galaxies, known until now, covering information
published up to January, 2000. In summary, 149 variables are presented
in our list for SX Phe-type variables belonging to 18 globular
clusters and 2 galaxies. Some relevant distributions are also shown.
The analysis of metal abundances and mean periods shows that both
parameters are correlated in the sense that the periods of the
variables are longer as the metallicity of the stellar system is
higher.
