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…
