RR Lyrae mode switching in globular cluster M 68 (NGC 4590)
N. Kains, D. M. Bramich, A. Arellano Ferro +1
We build on our detailed analysis of time-series observations of the globular cluster M 68 to investigate the irregular pulsational behaviour of four of the RR Lyrae stars in this…
Revisiting the variable star population in NGC~6229 and the structure of the Horizontal Branch
A. Arellano Ferro, P. E. Mancera Piña, D. M. Bramich +4
We report an analysis of new and CCD time-series photometry of the distant globular cluster NGC 6229. The principal aims were to explore the field of the cluster in search…
New variables in M5 (NGC 5904) and some identification corrections
A. Arellano Ferro, D. M. Bramich, S. Giridhar +2
We report twelve variables not previously detected in the globular cluster M5 (NGC 5904); one SX Phe and eleven semi-regular variables (SR). Their identifications, equatorial coord…
A Census of Variability in Globular Cluster M68 (NGC 4590)
N. Kains, A. Arellano Ferro, R. Figuera Jaimes +32
We analyse 20 nights of CCD observations in the V and I bands of the globular cluster M68 (NGC 4590), using these to detect variable objects. We also obtained electron-multiplying…
