A time-series VI study of the variable stars of the globular cluster NGC 6397
J. A. Ahumada, A. Arellano Ferro, I. Bustos Fierro +4
We present a new time-series VI CCD photometry of the globular cluster NGC 6397, from which we obtained and analysed the light curves of 35 variables carefully identified in the cl…
The globular cluster M10: Reassessment of stellar membership, distance and age using its variable and HB stars
A. Arellano Ferro, M. A. Yepez, S. Muneer +4
Time-series VI CCD photometry of the globular cluster M10 (NGC 6254) is employed to perform a detailed identification, inspection of their light curves, their classification and th…
NGC 6712: the variable star population of a tidally disrupted globular cluster
D. Deras, A. Arellano Ferro, C. Lázaro +4
We present an analysis of CCD time series photometry of globular cluster NGC 6712. Our main goal is to study the variable star population as indicators of the cluster m…
NGC 1261: A time-series \emph{VI} study of its variable stars
A. Arellano Ferro, I. H. Bustos Fierro, J. H. Calderón +1
Time-series \emph{VI} CCD photometry of the globular cluster NGC 1261 is employed to study its variable star population. A membership analysis of most variables based on Gaia~DR2 p…
Extraction of globular clusters members with Gaia DR2 astrometry
I. H. Bustos Fierro, J. H. Calderón
In this work we present a method to identify possible members of globular clusters using data from Gaia DR2. The method consists of two stages: the first one based on a clustering…
A new study of the variable star population in the Hercules globular cluster (M13; NGC 6205)
D. Deras, A. Arellano Ferro, C. Lázaro +4
We present the results from CCD time-series photometry of the globular cluster M13 (NGC 6205). From the Fourier decomposition of the light curves of RRab and RRc stars we foun…
