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…
Comprehensive abundance analysis of red giants in the open clusters NGC 1342, 1662, 1912, 2354 and 2447
Arumalla B. S. Reddy, Sunetra Giridhar, David L. Lambert
We have observed high-dispersion echelle spectra of red giant members in the five open clusters NGC 1342, NGC 1662, NGC 1912, NGC 2354 and NGC 2447 and determined their radial velo…
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…
