Variable stars in the field of the Galactic globular cluster M71
C. C. Cortés, D. Deras, A. Arellano Ferro +2
M71 is a nearby, metal-rich globular cluster at low Galactic latitude, where field contamination and spatially variable extinction complicate colour-magnitude diagrams (CMDs) and t…

Distance and [Fe/H] of Galactic bulge clusters from member RR Lyrae I-band light curves
A. Arellano Ferro, Z. Prudil
We have investigated the results for [Fe/H] and distance for a group of 24 globular clusters in the Galactic bulge, employing recent calibrations of RR Lyrae light curves Fourier d…

The variable stars in the compact halo globular cluster NGC 5634 visited again
A. Arellano Ferro, R. Michel, M. A. Yepez +3
We present new time-series CCD \emph{VR} photometry of the globular cluster NGC 5634. We aim to use the known RR Lyrae stars, members of the cluster, as indicators of mean metallic…
