NGC 6426: Colour-Magnitude diagram and variable star population as indicators of metallicity, distance, and age
A. Arellano Ferro, R. Michel, D. Deras +3
We present new VI CCD photometry of the globular cluster NGC 6426. The membership status of all point sources and, in particular, of all the variables in the field of view is discu…
A Homogenized Catalogue of Variable Stars in the Globular Cluster M22: Membership, Physical Parameters, and Distance
M. A. Yepez, B. Moreno-Amaro, M. Ornelas-Castañeda +2
We present a photometric analysis of the variable stars in the field of the globular cluster M22 (NGC 6656), using time-series photometry from the literature and from OGLE and Gaia…
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…
