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…
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…
Long term CCD photometry of the distant cluster NGC 2419: the CMD revisited
A. Arellano Ferro, S. Muneer, Sunetra Giridhar +4
Employing \emph{VI} images of NGC 2419 acquired over 17 years, light curves for most of the known variables in the field of the cluster are produced. A cluster membership analysis…
Star formation in the dwarf Seyfert galaxy NGC 4395: Evidence for both AGN and SNe feedback?
Payel Nandi, C. S. Stalin, D. J. Saikia +5
We present a detailed multi-wavelength study of star formation in the dwarf galaxy NGC 4395 which hosts an active galactic nucleus (AGN). From our observations with the Ultra-Viole…
Detailed analysis of the variable star population in the globular cluster NGC 7006
A. Arellano Ferro, F. C. Rojas Galindo, I. H. Bustos Fierro +3
A five year CCD photometric \emph{VI} time-series of NGC 7006 is employed to perform a detailed analysis of the known population of variable stars. In the process we have corrected…
RR Lyrae stars in the globular cluster Palomar 2
A. Arellano Ferro, I. Bustos Fierro, S. Muneer +1
A CCD VI imaging time-series over 11-year is employed to explore the light curves of stars in the field of Palomar 2. We discovered 20 RRab and 1 RRc variables. A revision of Gaia-…
